2008-12-16ocfs2: Always update xattr search when creating bucket.Tao Ma
When we create xattr bucket during the process of xattr set, we always need to update the ocfs2_xattr_search since even if the bucket size is the same as block size, the offset will change because of the removal of the ocfs2_xattr_block header.

2008-12-01ocfs2: fix regression in ocfs2_read_blocks_sync()Mark Fasheh
We're panicing in ocfs2_read_blocks_sync() if a jbd-managed buffer is seen. At first glance, this seems ok but in reality it can happen. My test case was to just run 'exorcist'. A struct inode is being pushed out of memory but is then re-read at a later time, before the buffer has been checkpointed by jbd. This causes a BUG to be hit in ocfs2_read_blocks_sync().

2008-11-14CRED: Wrap task credential accesses in the OCFS2 filesystemDavid Howells
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.

2008-11-10ocfs2: Check search result in ocfs2_xattr_block_get()Tiger Yang
ocfs2_xattr_block_get() calls ocfs2_xattr_search() to find an external xattr, but doesn't check the search result that is passed back via struct ocfs2_xattr_search. Add a check for search result, and pass back -ENODATA if the xattr search failed. This avoids a later NULL pointer error.

2008-11-10ocfs2/xattr: Proper hash collision handle in bucket divisionTao Ma
In ocfs2/xattr, we must make sure the xattrs which have the same hash value exist in the same bucket so that the search schema can work. But in the old implementation, when we want to extend a bucket, we just move half number of xattrs to the new bucket. This works in most cases, but if we are lucky enough we will move 2 xattrs into 2 different buckets. This means that an xattr from the previous bucket cannot be found anymore. This patch fix this problem by finding the right position during extending the bucket and extend an empty bucket if needed.

2008-11-10ocfs2: return 0 in page_mkwrite to let VFS retry.Tao Ma
In ocfs2_page_mkwrite, we return -EINVAL when we found the page mapping isn't updated, and it will cause the user space program get SIGBUS and exit. The reason is that during race writeable mmap, we will do unmap_mapping_range in ocfs2_data_downconvert_worker. The good thing is that if we reuturn 0 in page_mkwrite, VFS will retry fault and then call page_mkwrite again, so it is safe to return 0 here.

2008-11-10ocfs2: Set journal descriptor to NULL after journal shutdownSunil Mushran
