ext3: skip orphan cleanup on rocompat fs

2011-03-27T18:35:59Z

commit ce654b37f87980d95f339080e4c3bdb2370bdf22 upstream. Orphan cleanup is currently executed even if the file system has some number of unknown ROCOMPAT features, which deletes inodes and frees blocks, which could be very bad for some RO_COMPAT features. This patch skips the orphan cleanup if it contains readonly compatible features not known by this ext3 implementation, which would prevent the fs from being mounted (or remounted) readwrite.

ext3: Always set dx_node's fake_dirent explicitly.

2011-03-23T20:04:06Z

commit d7433142b63d727b5a217c37b1a1468b116a9771 upstream. (crossport of 1f7bebb9e911d870fa8f997ddff838e82b5715ea by Andreas Schlick ) When ext3_dx_add_entry() has to split an index node, it has to ensure that name_len of dx_node's fake_dirent is also zero, because otherwise e2fsck won't recognise it as an intermediate htree node and consider the htree to be corrupted.

quota: Fix deadlock during path resolution

2011-01-12T18:14:55Z

As Al Viro pointed out path resolution during Q_QUOTAON calls to quotactl is prone to deadlocks. We hold s_umount semaphore for reading during the path resolution and resolution itself may need to acquire the semaphore for writing when e. g. autofs mountpoint is passed. Solve the problem by performing the resolution before we get hold of the superblock (and thus s_umount semaphore). The whole thing is complicated by the fact that some filesystems (OCFS2) ignore the path argument. So to distinguish between filesystem which want the path and which do not we introduce new .quota_on_meta callback which does not get the path. OCFS2 then uses this callback instead of old .quota_on.

ext3: speed up file creates by optimizing rec_len functions

2011-01-10T18:04:07Z

The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks, thanks to page size limits. Similar changes already exist in the ext4 codebase. The directory entry checking can also be optimized a bit by sprinkling in some unlikely() conditions to move the error handling out of line. bonnie++ sequential file creates on a 512MB ramdisk speeds up from about 77,000/s to about 82,000/s, about a 6% improvement.
