This patch renames n_, c_, etc variables to something more sane. This is the sixth in a series of patches to rip out some of the awful variable naming in reiserfs. Signed-off-by:

This patch cleans up some redundancies in the reiserfs tree path code. decrement_bcount() is essentially the same function as brelse(), so we use that instead. decrement_counters_in_path() is exactly the same function as pathrelse(), so we kill that and use pathrelse() instead. There's also a bit of cleanup that makes the code a bit more readable. Signed-off-by:

This is the first in a series of patches to make balance_leaf() not quite so insane. This patch factors out the open coded initializations of buffer_info structures and defines a few initializers for the 4 cases they're used. Signed-off-by:

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. Signed-off-by:

The current reiserfs xattr implementation open codes reiserfs_readdir and frees the path before calling the filldir function. Typically, the filldir function is something that modifies the file system, such as a chown or an inode deletion that also require reading of an inode associated with each direntry. Since the file system is modified, the path retained becomes invalid for the next run. In addition, it runs backwards in attempt to minimize activity. This is clearly suboptimal from a code cleanliness perspective as well as performance-wise. This patch implements a generic reiserfs_for_each_xattr that uses the generic readdir and a specific filldir routine that simply populates an array of dentries and then performs a specific operation on them. When all files have been operated on, it then calls the operation on the directory itself. The result is a noticable code reduction and better performance. Signed-off-by:

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.

Christoph Hellwig had asked me quite some time ago to port the reiserfs xattrs to the generic xattr interface. This patch replaces the reiserfs-specific xattr handling code with the generic struct xattr_handler. However, since reiserfs doesn't split the prefix and name when accessing xattrs, it can't leverage generic_{set,get,list,remove}xattr without needlessly reconstructing the name on the back end. Update 7/26/07: Added missing dput() to deletion path. Update 8/30/07: Added missing mark_inode_dirty when i_mode is used to represent an ACL and no previous ACL existed. Signed-off-by: -

With the changes to xattr root locking, the i_has_xattr_dir flag is no longer needed. This patch removes it. Signed-off-by:

The per-inode locking can be made more fine-grained to surround just the interaction with the filesystem itself. This really only applies to protecting reads during a write, since concurrent writes are barred with inode->i_mutex at the vfs level. Signed-off-by:

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:

The xattr file open/lookup code is needlessly complex. We can use vfs-level operations to perform the same work, and also simplify the locking constraints. The locking advantages will be exploited in future patches. Signed-off-by:

The current reiserfs xattr implementation will not clean up old xattr files if files are deleted when REISERFS_FS_XATTR is unset. This results in inaccessible lost files, wasting space. This patch compiles in basic xattr knowledge, such as how to delete them and change ownership for quota tracking. If the file system has never used xattrs, then the operation is quite fast: it returns immediately when it sees there is no .reiserfs_priv directory. Signed-off-by:

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. Signed-off-by:

Early in the reiserfs xattr development, there was a plan to use hardlinks to save disk space for identical xattrs. That code never materialized and isn't going to, so this patch removes the detection code. Signed-off-by:

Although reiserfs can currently handle severe errors such as journal failure, it cannot handle less severe errors like metadata i/o failure. The following patch adds a reiserfs_error() function akin to the one in ext3. Subsequent patches will use this new error handler to handle errors more gracefully in general. Signed-off-by:

This patch kills off reiserfs_journal_abort as it is never called, and combines __reiserfs_journal_abort_{soft,hard} into one function called reiserfs_abort_journal, which performs the same work. It is silent as opposed to the old version, since the message was always issued after a regular 'abort' message. Signed-off-by: -

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. Signed-off-by:

The formatting of the error buffer is race prone. It uses static buffers for both formatting and output. While overwriting the error buffer can product garbled output, overwriting the format buffer with incompatible % directives can cause crashes. Signed-off-by:

uniqueness2type and type2uniquness issue a warning when the value is unknown. When called from reiserfs_warning, this causes a re-entrancy problem and deadlocks on the error buffer lock. Signed-off-by:

vsprintf will consume varargs on its own. Skipping them manually results in garbage in the error buffer, or Oopses in the case of pointers. This patch removes the advancement and fixes a number of bugs where crashes were observed as side effects of a regular error report. Signed-off-by:

This patch makes leaf_paste_entries more consistent with respect to the other leaf operations. Using buffer_info instead of buffer_head directly allows us to get a superblock pointer for use in error handling. Signed-off-by:

This patch fixes up the reiserfs code such that transaction ids are always unsigned ints. In places they can currently be signed ints or unsigned longs. The former just causes an annoying clm-2200 warning and may join a transaction when it should wait. The latter is just for correctness since the disk format uses a 32-bit transaction id. There aren't any runtime problems that result from it not wrapping at the correct location since the value is truncated correctly even on big endian systems. The 0 value might make it to disk, but the mount-time checks will bump it to 10 itself. Signed-off-by:

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.) Signed-off-by:
