Since all 4 files, localalloc.c, suballoc.c, alloc.c and resize.c, which use DISK_ALLOC are changed to trace events, Remove masklog DISK_ALLOC totally. Signed-off-by: Tao Ma <boyu.mt@taobao.com>
2011-03-07ocfs2: Remove EXIT from masklog.Tao Ma1-44/+0
mlog_exit is used to record the exit status of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. This patch just try to remove it or change it. So: 1. if all the error paths already use mlog_errno, it is just removed. Otherwise, it will be replaced by mlog_errno. 2. if it is used to print some return value, it is replaced with mlog(0,...). mlog_exit_ptr is changed to mlog(0. All those mlog(0,...) will be replaced with trace events later. Signed-off-by: Tao Ma <boyu.mt@taobao.com>
2011-02-21ocfs2: Remove ENTRY from masklog.Tao Ma1-12/+1
ENTRY is used to record the entry of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. So for mlog_entry_void, we just remove it. for mlog_entry(...), we replace it with mlog(0,...), and they will be replace by trace event later. Signed-off-by: Tao Ma <boyu.mt@taobao.com>

2010-05-06ocfs2: allocation reservationsMark Fasheh1-0/+1
This patch improves Ocfs2 allocation policy by allowing an inode to reserve a portion of the local alloc bitmap for itself. The reserved portion (allocation window) is advisory in that other allocation windows might steal it if the local alloc bitmap becomes full. Otherwise, the reservations are honored and guaranteed to be free. When the local alloc window is moved to a different portion of the bitmap, existing reservations are discarded. Reservation windows are represented internally by a red-black tree. Within that tree, each node represents the reservation window of one inode. An LRU of active reservations is also maintained. When new data is written, we allocate it from the inodes window. When all bits in a window are exhausted, we allocate a new one as close to the previous one as possible. Should we not find free space, an existing reservation is pulled off the LRU and cannibalized. Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2010-02-28ocfs2: Use a separate masklog for AST and BASTsSunil Mushran1-0/+1
This patch adds a new masklog and uses it allow tracing ASTs and BASTs in the dlmglue layer. This has been found to be very useful in debugging cluster locking issues. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

2009-05-06ocfs2: update comments in masklog.hColy Li1-18/+17
In the mainline ocfs2 code, the interface for masklog is in files under /sys/fs/o2cb/masklog, but the comments in fs/ocfs2/cluster/masklog.h reference the old /proc interface. They are out of date. This patch modifies the comments in cluster/masklog.h, which also provides a bash script example on how to change the log mask bits.

2009-01-05ocfs2: Implementation of local and global quota file handlingJan Kara1-0/+1
For each quota type each node has local quota file. In this file it stores changes users have made to disk usage via this node. Once in a while this information is synced to global file (and thus with other nodes) so that limits enforcement at least aproximately works. Global quota files contain all the information about usage and limits. It's mostly handled by the generic VFS code (which implements a trie of structures inside a quota file). We only have to provide functions to convert structures from on-disk format to in-memory one. We also have to provide wrappers for various quota functions starting transactions and acquiring necessary cluster locks before the actual IO is really started.

2008-10-14ocfs2: Add extent tree operation for xattr value btreesTao Ma1-0/+1
Add some thin wrappers around ocfs2_insert_extent() for each of the 3 different btree types, ocfs2_inode_insert_extent(), ocfs2_xattr_value_insert_extent() and ocfs2_xattr_tree_insert_extent(). The last is for the xattr index btree, which will be used in a followup patch. All the old callers in file.c etc will call ocfs2_dinode_insert_extent(), while the other two handle the xattr issue. And the init of extent tree are handled by these functions. When storing xattr value which is too large, we will allocate some clusters for it and here ocfs2_extent_list and ocfs2_extent_rec will also be used. In order to re-use the b-tree operation code, a new parameter named "private" is added into ocfs2_extent_tree and it is used to indicate the root of ocfs2_exent_list. The reason is that we can't deduce the root from the buffer_head now. It may be in an inode, an ocfs2_xattr_block or even worse, in any place in an ocfs2_xattr_bucket.

2007-10-19Use helpers to obtain task pid in printksPavel Emelyanov1-1/+1
The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

2007-05-03remove "struct subsystem" as it is no longer neededGreg Kroah-Hartman1-1/+1
We need to work on cleaning up the relationship between kobjects, ksets and ktypes. The removal of 'struct subsystem' is the first step of this, especially as it is not really needed at all. Thanks to Kay for fixing the bugs in this patch. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-06-30ocfs2: Compile-time disabling of ocfs2 debugging output.Joel Becker1-1/+21

2006-03-01[PATCH] ocfs2: fix -Wformat warnings when building UML on x86-64Jeff Mahoney1-1/+1
The check to determine which format string is appopriate for u64 and friends works in most cases, but UML on x86_64 doesn't define CONFIG_X86_64, so it results in screen fulls of compile-time warnings. This patch fixes it to handle that case. fs/ocfs2/cluster/masklog.h | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
