* [PATCH] sysfs: fix a kobject leak in sysfs_add_link on the error pathGreg Kroah-Hartman2006-03-201-0/+1

* [PATCH] sysfs: don't export dir symbolsGreg Kroah-Hartman2006-03-201-4/+0
| | | | | | | | These functions should only be used by the kobject core, and if any driver tries to use them, bad things happen. Unexport them to try to prevent this from happening. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] sysfs: sysfs_remove_dir() needs to invalidate the dentryGreg Kroah-Hartman2006-03-202-1/+6
| | | | | | | | | | | | | | When calling sysfs_remove_dir() don't allow any further sysfs functions to work for this kobject anymore. This fixes a nasty USB cdc-acm oops on disconnect. Many thanks to Bob Copeland and Paul Fulghum for taking the time to track this down.

* [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen2006-01-094-33/+28
| | | | | | | | | | | | | This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.

* [PATCH] Fix oops in sysfs_hash_and_remove_file()James Bottomley2005-08-261-0/+4
| | | | | | | | | | | | | | | | | | | The problem arises if an entity in sysfs is created and removed without ever having been made completely visible. In SCSI this is triggered by removing a device while it's initialising. The problem appears to be that because it was never made visible in sysfs, the sysfs dentry has a null d_inode which oopses when a reference is made to it. The solution is simply to check d_inode and assume the object was never made visible (and thus doesn't need deleting) if it's NULL. (akpm: possibly a stopgap for 2.6.13 scsi problems. May not be the long-term fix) Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Fix nasty ncpfs symlink handling bug.Linus Torvalds2005-08-191-3/+3
| | | | | | | | | | | | | | | | | | This bug could cause oopses and page state corruption, because ncpfs used the generic page-cache symlink handlign functions. But those functions only work if the page cache is guaranteed to be "stable", ie a page that was installed when the symlink walk was started has to still be installed in the page cache at the end of the walk. We could have fixed ncpfs to not use the generic helper routines, but it is in many ways much cleaner to instead improve on the symlink walking helper routines so that they don't require that absolute stability. We do this by allowing "follow_link()" to return a error-pointer as a cookie, which is fed back to the cleanup "put_link()" routine. This also simplifies NFS symlink handling.

* [PATCH] sysfs: fix sysfs_setattrManeesh Soni2005-07-291-1/+1
| | | | | | | | | | o sysfs_dirent's s_mode field should also be updated in sysfs_setattr(), else there could be inconsistency in the two fields. s_mode is used while ->readdir so as not to bring in the inode to cache.

* [PATCH] inotifyRobert Love2005-07-121-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] remove duplicate get_dentry functions in various placesChristoph Hellwig2005-06-235-16/+9
| | | | | | | | | | | | | | Various filesystem drivers have grown a get_dentry() function that's a duplicate of lookup_one_len, except that it doesn't take a maximum length argument and doesn't check for \0 or / in the passed in filename. Switch all these places to use lookup_one_len.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-169-0/+1763
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
