Linux 2.6.13-rc3

Yeah, this time hopefully I'm not confusing the version numbers. The last release was -rc2, _this_ is -rc3.

[PATCH] inotify

2005-07-13T03:38:38+00:00

inotify is intended to correct the deficiencies of dnotify, particularly its inability to scale and its terrible user interface: * dnotify requires the opening of one fd per each directory that you intend to watch. This quickly results in too many open files and pins removable media, preventing unmount. * dnotify is directory-based. You only learn about changes to directories. Sure, a change to a file in a directory affects the directory, but you are then forced to keep a cache of stat structures. * dnotify's interface to user-space is awful. Signals? inotify provides a more usable, simple, powerful solution to file change notification: * inotify's interface is a system call that returns a fd, not SIGIO. You get a single fd, which is select()-able. * inotify has an event that says "the filesystem that the item you were watching is on was unmounted." * inotify can watch directories or files. Inotify is currently used by Beagle (a desktop search infrastructure), Gamin (a FAM replacement), and other projects. See Documentation/filesystems/inotify.txt.

reiserfs: run scripts/Lindent on reiserfs code

2005-07-13T03:21:28+00:00

This was a pure indentation change, using: scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h to make reiserfs match the regular Linux indentation style. As Jeff Mahoney writes: The ReiserFS code is a mix of a number of different coding styles, sometimes different even from line-to-line. Since the code has been relatively stable for quite some time and there are few outstanding patches to be applied, it is time to reformat the code to conform to the Linux style standard outlined in Documentation/CodingStyle. This patch contains the result of running scripts/Lindent against fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the code can be made to look better, but I'd rather keep those patches separate so that there isn't a subtle by-hand hand accident in the middle of a huge patch. To be clear: This patch is reformatting *only*. A number of patches may follow that continue to make the code more consistent with the Linux coding style. Hans wasn't particularly enthusiastic about these patches, but said he wouldn't really oppose them either. Signed-off-by: Linus Torvalds

[PATCH] reiserfs: fix up case where indent misreads the code

2005-07-12T23:22:35+00:00

indent(1) doesn't know how to handle the "do not compile" error. It results in the item_ops array declaration being indented a tab stop in when it should not be. This patch replaces it with a #error that describes why it's failing. Signed-off-by: Jeff Mahoney Signed-off-by: Linus Torvalds

[PATCH] device-mapper: Fix dm_swap_table error cases

2005-07-12T23:19:11+00:00

Fix dm_swap_table() __bind error cases: a missing unlock, and EINVAL preferable to EPERM. Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] device-mapper multipath: Fix pg initialisation races

2005-07-12T23:19:11+00:00

Prevent more than one priority group initialisation function from being outstanding at once. Otherwise the completion functions interfere with each other. Also, reloading the table could reference a freed pointer. Only reset queue_io in pg_init_complete if another pg_init isn't required. Skip process_queued_ios if the queue is empty so that we only trigger a pg_init if there's I/O.

[PATCH] device-mapper multipath: Avoid possible suspension deadlock

2005-07-12T23:19:10+00:00

To avoid deadlock when suspending a multipath device after all its paths have failed, stop queueing any I/O that is about to fail *before* calling freeze_bdev instead of after. Instead of setting a multipath 'suspended' flag which would have to be reset if an error occurs during the process, save the previous queueing state and leave userspace to restore if it wishes.

[PATCH] device-mapper multipath: Flush workqueue when destroying

2005-07-12T23:19:10+00:00

The multipath destructor must flush its workqueue. Otherwise items that reference the destroyed object could remain. From: "goggin, edward" Signed-off-by: Lars Marowsky-Bree Signed-off-by: Alasdair G Kergon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
