This patch turns on barriers by default for ext3. mount -o barrier=0 will turn them off. Based on a patch from Chris Mason in the SuSE tree.

This commit adds fixed tracepoints to the ext3 code. It is based on ext4 tracepoints, however due to the differences of both file systems, there are some tracepoints missing (those for delaloc and for multi-block allocator) and there are some ext3 specific as well (for reservation windows). Here is a list: ext3_free_inode ext3_request_inode ext3_allocate_inode ext3_evict_inode ext3_drop_inode ext3_mark_inode_dirty ext3_write_begin ext3_ordered_write_end ext3_writeback_write_end ext3_journalled_write_end ext3_ordered_writepage ext3_writeback_writepage ext3_journalled_writepage ext3_readpage ext3_releasepage ext3_invalidatepage ext3_discard_blocks ext3_request_blocks ext3_allocate_blocks ext3_free_blocks ext3_sync_file_enter ext3_sync_file_exit ext3_sync_fs ext3_rsv_window_add ext3_discard_reservation ext3_alloc_new_reservation ext3_reserved ext3_forget ext3_read_block_bitmap ext3_direct_IO_enter ext3_direct_IO_exit ext3_unlink_enter ext3_unlink_exit ext3_truncate_enter ext3_truncate_exit ext3_get_blocks_enter ext3_get_blocks_exit ext3_load_inode Signed-off-by: Lukas Czerner <lczerner@redhat.com> Cc: Jan Kara <jack@suse.cz> Signed-off-by: Jan Kara <jack@suse.cz>
This fifth patch of eight in this cleancache series "opts-in" cleancache for ext3. Filesystems must explicitly enable cleancache by calling cleancache_init_fs anytime an instance of the filesystem is mounted. For ext3, all other cleancache hooks are in the VFS layer including the matching cleancache_flush_fs hook which must be called on unmount. Details and a FAQ can be found in Documentation/vm/cleancache.txt [v6-v8: no changes] [v5: jeremy@goop.org: simplify init hook and any future fs init changes] Signed-off-by: Dan Magenheimer <dan.magenheimer@oracle.com> Reviewed-by: Jeremy Fitzhardinge <jeremy@goop.org> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Acked-by: Andreas Dilger <adilger@sun.com> Cc: Ted Ts'o <tytso@mit.edu> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Al Viro <viro@ZenIV.linux.org.uk> Cc: Matthew Wilcox <matthew@wil.cx> Cc: Nick Piggin <npiggin@kernel.dk> Cc: Mel Gorman <mel@csn.ul.ie> Cc: Rik Van Riel <riel@redhat.com> Cc: Jan Beulich <JBeulich@novell.com> Cc: Chris Mason <chris.mason@oracle.com> Cc: Mark Fasheh <mfasheh@suse.com> Cc: Joel Becker <joel.becker@oracle.com> Cc: Nitin Gupta <ngupta@vflare.org>

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.
