Message-ID: <nsxbo6mxu38.fsf@lambda.thunk.org> Date: Mon, 01 Jul 2013 09:55:55 -0400 From: Theodore Ts'o <tytso@....edu> To: Linus Torvalds <torvalds@...ux-foundation.org> cc: linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [GIT PULL] ext4 updates for 3.11 The following changes since commit c7788792a5e7b0d5d7f96d0766b4cb6112d47d75: Linux 3.10-rc2 (2013-05-20 14:37:38 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git tags/ext4_for_linus for you to fetch changes up to 6ae06ff51eab5dcbbf959b05ce0f11003a305ba5: ext4: optimize starting extent in ext4_ext_rm_leaf() (2013-07-01 08:12:41 -0400) ---------------------------------------------------------------- Lots of bug fixes, cleanups and optimizations. In the bug fixes category, of note is a fix for on-line resizing file systems where the block size is smaller than the page size (i.e., file systems 1k blocks on x86, or more interestingly file systems with 4k blocks on Power or ia64 systems.) In the cleanup category, the ext4's punch hole implementation was significantly improved by Lukas Czerner, and now supports bigalloc file systems. In addition, Jan Kara significantly cleaned up the write submission code path. We also improved error checking and added a few sanity checks. In the optimizations category, two major optimizations deserve mention. The first is that ext4_writepages() is now used for nodelalloc and ext3 compatibility mode. This allows writes to be submitted much more efficiently as a single bio request, instead of being sent as individual 4k writes into the block layer (which then relied on the elevator code to coalesce the requests in the block queue). Secondly, the extent cache shrink mechanism, which was introduce in 3.9, no longer has a scalability bottleneck caused by the i_es_lru spinlock. Other optimizations include some changes to reduce CPU usage and to avoid issuing empty commits unnecessarily. ---------------------------------------------------------------- Al Viro (1): ext3,ext4: don't mess with dir_file->f_pos in htree_dirblock_to_tree() Alexey Khoroshilov (1): ext4: implement error handling of ext4_mb_new_preallocation() Ashish Sangwan (2): ext4: pass inode pointer instead of file pointer to punch hole ext4: optimize starting extent in ext4_ext_rm_leaf() Darrick J.
