2009-05-09reiserfs: remove privroot hiding in lookupJeff Mahoney1-15/+2
With Al Viro's patch to move privroot lookup to fs mount, there's no need to have special code to hide the privroot in reiserfs_lookup. I've also cleaned up the privroot hiding in reiserfs_readdir_dentry and removed the last user of reiserfs_xattrs().

2009-03-30reiserfs: add atomic addition of selinux attributes during inode creationJeff Mahoney1-4/+33
Some time ago, some changes were made to make security inode attributes be atomically written during inode creation. ReiserFS fell behind in this area, but with the reworking of the xattr code, it's now fairly easy to add. The following patch adds the ability for security attributes to be added automatically during inode creation.

2009-03-30reiserfs: journaled xattrsJeff Mahoney1-11/+3
Deadlocks are possible in the xattr code between the journal lock and the xattr sems. This patch implements journalling for xattr operations. The benefit is twofold: * It gets rid of the deadlock possibility by always ensuring that xattr write operations are initiated inside a transaction. * It corrects the problem where xattr backing files aren't considered any differently than normal files, despite the fact they are metadata. I discussed the added journal load with Chris Mason, and we decided that since xattrs (versus other journal activity) is fairly rare, the introduction of larger transactions to support journaled xattrs wouldn't be too big a deal.

2009-03-30reiserfs: eliminate per-super xattr lockJeff Mahoney1-29/+0
With the switch to using inode->i_mutex locking during lookups/creation in the xattr root, the per-super xattr lock is no longer needed. This patch removes it. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-03-30reiserfs: remove IS_PRIVATE helpersJeff Mahoney1-3/+4
There are a number of helper functions for marking a reiserfs inode private that were leftover from reiserfs did its own thing wrt to private inodes. S_PRIVATE has been in the kernel for some time, so this patch removes the helpers and uses IS_PRIVATE instead.

2009-03-30reiserfs: rework reiserfs_panicJeff Mahoney1-10/+8
ReiserFS panics can be somewhat inconsistent. In some cases: * a unique identifier may be associated with it * the function name may be included * the device may be printed separately This patch aims to make warnings more consistent. reiserfs_warning() prints the device name, so printing it a second time is not required. The function name for a warning is always helpful in debugging, so it is now automatically inserted into the output. Hans has stated that every warning should have a unique identifier. Some cases lack them, others really shouldn't have them. reiserfs_warning() now expects an id associated with each message. In the rare case where one isn't needed, "" will suffice.

2008-11-14CRED: Wrap task credential accesses in the ReiserFS filesystemDavid Howells1-2/+2
Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

2007-02-12[PATCH] mark struct inode_operations const 3Arjan van de Ven1-3/+3
Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-10-01[PATCH] r/o bind mounts: monitor zeroing of i_nlinkDave Hansen1-2/+2

2006-10-01[PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen1-3/+3
When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

2005-07-12reiserfs: run scripts/Lindent on reiserfs codeLinus Torvalds1-1244/+1330
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 <jeffm@suse.com> 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 <torvalds@osdl.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+1491
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!
