+ * lowcomms.c
+ *
+ * This is the "low-level" comms layer.
+ *
+ * It is responsible for sending/receiving messages
+ * from other nodes in the cluster.
+ *
+ * Cluster nodes are referred to by their nodeids. nodeids are
+ * simply 32 bit numbers to the locking module - if they need to
+ * be expanded for the cluster infrastructure then that is it's
+ * responsibility. It is this layer's
+ * responsibility to resolve these into IP address or
+ * whatever it needs for inter-node communication.
+ *
+ * The comms level is two kernel threads that deal mainly with
+ * the receiving of messages from other nodes and passing them
+ * up to the mid-level comms layer (which understands the
+ * message format) for execution by the locking core, and
+ * a send thread which does all the setting up of connections
+ * to remote nodes and the sending of data. Threads are not allowed
+ * to send their own data because it may cause them to wait in times
+ * of high load. Also, this way, the sending thread can collect together
+ * messages bound for one node and send them in one block.
+ *
+ * I don't see any problem with the recv thread executing the locking
+ * code on behalf of remote processes as the locking code is
+ * short, efficient and never waits.

- * inode.c: corrected 1 track offset setting (in sb->sv_block_base).
- Originally it was overridden (by setting to zero)
- in detected_[xenix,sysv4,sysv2,coherent]. Thanks

- for identifying the problem.
-
-Tue, 27 Jan 1998 Krzysztof G. Baranowski <kgb@manjak.knm.org.pl>
- * inode.c: added 2048-byte block support to SystemV FS.
- Merged detected_bs[512,1024,2048]() into one function:
- void detected_bs (u_char type, struct super_block *sb).
- Thanks to Andrzej Krzysztofowicz <ankry@mif.pg.gda.pl>
- for the patch.
-
-Wed, 4 Feb 1998 Krzysztof G. Baranowski <kgb@manjak.knm.org.pl>

- is used instead. Cosmetic changes.
-
-Thu, 3 Dec 1998 Al Viro (viro@parcelfarce.linux.theplanet.co.uk)
- * namei.c (sysv_rmdir):
- Bugectomy: old check for victim being busy
- (inode->i_count) wasn't replaced (with checking
- dentry->d_count) and escaped Linus in the last round
- of changes. Shot and buried.
-
-Wed, 9 Dec 1998 AV
- * namei.c (do_sysv_rename):
- Fixed incorrect check for other owners + race.
- Removed checks that went to VFS.
- * namei.c (sysv_unlink):
- Removed checks that went to VFS.
-
-Thu, 10 Dec 1998 AV
- * namei.c (do_mknod):
- Removed dead code - mknod is never asked to
- create a symlink or directory. Incidentially,
- it wouldn't do it right if it would be called.
-
-Sat, 26 Dec 1998 KGB
- * inode.c (detect_sysv4):
- Added detection of expanded s_type field (0x10,
- 0x20 and 0x30). Forced read-only access in this case.
-
-Sun, 21 Mar 1999 AV
- * namei.c (sysv_link):
- Fixed i_count usage that resulted in dcache corruption.
- * inode.c:
- Filled ->delete_inode() method with sysv_delete_inode().
- sysv_put_inode() is gone, as it tried to do ->delete_
- _inode()'s job.
- * ialloc.c: (sysv_free_inode):
- Fixed race.
-
-Sun, 30 Apr 1999 AV
- * namei.c (sysv_mknod):

-This is the implementation of the SystemV/Coherent filesystem for Linux.
-It grew out of separate filesystem implementations
-
- Xenix FS Doug Evans <dje@cygnus.com> June 1992

- Coherent FS B. Haible <haible@ma2s2.mathematik.uni-karlsruhe.de> June 1993
-
-and was merged together in July 1993.
-
-These filesystems are rather similar. Here is a comparison with Minix FS:
-
-* Linux fdisk reports on partitions
- - Minix FS 0x81 Linux/Minix
- - Xenix FS ??
- - SystemV FS ??
- - Coherent FS 0x08 AIX bootable
-
-* Size of a block or zone (data allocation unit on disk)
- - Minix FS 1024
- - Xenix FS 1024 (also 512 ??)
- - SystemV FS 1024 (also 512 and 2048)
- - Coherent FS 512
-
-* General layout: all have one boot block, one super block and
- separate areas for inodes and for directories/data.
- On SystemV Release 2 FS (e.g. Microport) the first track is reserved and
- all the block numbers (including the super block) are offset by one track.
-
-* Byte ordering of "short" (16 bit entities) on disk:
- - Minix FS little endian 0 1
- - Xenix FS little endian 0 1
- - SystemV FS little endian 0 1
- - Coherent FS little endian 0 1
- Of course, this affects only the file system, not the data of files on it!
-
-* Byte ordering of "long" (32 bit entities) on disk:
- - Minix FS little endian 0 1 2 3
- - Xenix FS little endian 0 1 2 3
- - SystemV FS little endian 0 1 2 3
- - Coherent FS PDP-11 2 3 0 1
- Of course, this affects only the file system, not the data of files on it!
-
-* Inode on disk: "short", 0 means non-existent, the root dir ino is:
- - Minix FS 1
- - Xenix FS, SystemV FS, Coherent FS 2
-
-* Maximum number of hard links to a file:
- - Minix FS 250
- - Xenix FS ??
- - SystemV FS ??
- - Coherent FS >=10000
-
-* Free inode management:
- - Minix FS a bitmap
- - Xenix FS, SystemV FS, Coherent FS
- There is a cache of a certain number of free inodes in the super-block.
- When it is exhausted, new free inodes are found using a linear search.
-
-* Free block management:
- - Minix FS a bitmap
- - Xenix FS, SystemV FS, Coherent FS
- Free blocks are organized in a "free list". Maybe a misleading term,
- since it is not true that every free block contains a pointer to
- the next free block. Rather, the free blocks are organized in chunks
- of limited size, and every now and then a free block contains pointers
- to the free blocks pertaining to the next chunk; the first of these
- contains pointers and so on. The list terminates with a "block number"
- 0 on Xenix FS and SystemV FS, with a block zeroed out on Coherent FS.
-
-* Super-block location:
- - Minix FS block 1 = bytes 1024..2047
- - Xenix FS block 1 = bytes 1024..2047
- - SystemV FS bytes 512..1023
- - Coherent FS block 1 = bytes 512..1023
-
-* Super-block layout:
- - Minix FS
- unsigned short s_ninodes;
- unsigned short s_nzones;
- unsigned short s_imap_blocks;
- unsigned short s_zmap_blocks;
- unsigned short s_firstdatazone;
- unsigned short s_log_zone_size;
- unsigned long s_max_size;
- unsigned short s_magic;
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short s_firstdatazone;
- unsigned long s_nzones;
- unsigned short s_fzone_count;
- unsigned long s_fzones[NICFREE];
- unsigned short s_finode_count;
- unsigned short s_finodes[NICINOD];
- char s_flock;
- char s_ilock;
- char s_modified;
- char s_rdonly;
- unsigned long s_time;
- short s_dinfo[4]; -- SystemV FS only
- unsigned long s_free_zones;
- unsigned short s_free_inodes;
- short s_dinfo[4]; -- Xenix FS only
- unsigned short s_interleave_m,s_interleave_n; -- Coherent FS only
- char s_fname[6];
- char s_fpack[6];
- then they differ considerably:
- Xenix FS
- char s_clean;
- char s_fill[371];
- long s_magic;
- long s_type;
- SystemV FS
- long s_fill[12 or 14];
- long s_state;
- long s_magic;
- long s_type;
- Coherent FS
- unsigned long s_unique;
- Note that Coherent FS has no magic.
-
-* Inode layout:
- - Minix FS
- unsigned short i_mode;
- unsigned short i_uid;
- unsigned long i_size;
- unsigned long i_time;
- unsigned char i_gid;
- unsigned char i_nlinks;
- unsigned short i_zone[7+1+1];
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short i_mode;
- unsigned short i_nlink;
- unsigned short i_uid;
- unsigned short i_gid;
- unsigned long i_size;
- unsigned char i_zone[3*(10+1+1+1)];
- unsigned long i_atime;
- unsigned long i_mtime;
- unsigned long i_ctime;
-
-* Regular file data blocks are organized as
- - Minix FS
- 7 direct blocks
- 1 indirect block (pointers to blocks)
- 1 double-indirect block (pointer to pointers to blocks)
- - Xenix FS, SystemV FS, Coherent FS
- 10 direct blocks
- 1 indirect block (pointers to blocks)
- 1 double-indirect block (pointer to pointers to blocks)
- 1 triple-indirect block (pointer to pointers to pointers to blocks)
-
-* Inode size, inodes per block
- - Minix FS 32 32
- - Xenix FS 64 16
- - SystemV FS 64 16
- - Coherent FS 64 8
-
-* Directory entry on disk
- - Minix FS
- unsigned short inode;
- char name[14/30];
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short inode;
- char name[14];
-
-* Dir entry size, dir entries per block
- - Minix FS 16/32 64/32
- - Xenix FS 16 64
- - SystemV FS 16 64
- - Coherent FS 16 32
-
-* How to implement symbolic links such that the host fsck doesn't scream:
- - Minix FS normal
- - Xenix FS kludge: as regular files with chmod 1000
- - SystemV FS ??
- - Coherent FS kludge: as regular files with chmod 1000
-
-
-Notation: We often speak of a "block" but mean a zone (the allocation unit)
-and not the disk driver's notion of "block".
