Hi all, This final series ports the libext2fs inode cache to the new cache.c hashtable code that was added for fuse4fs unlinked file support and improves on the UNIX I/O manager's block cache by adding a new I/O manager that does its own caching. Now we no longer have statically sized buffer caching for the two fuse servers. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. Comments and questions are, as always, welcome. e2fsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/e2fsprogs.git/log/?h=fuse2fs-caching --- Commits in this patchset: * libsupport: add caching IO manager * iocache: add the actual buffer cache * iocache: bump buffer mru priority every 50 accesses * fuse2fs: enable caching IO manager * fuse2fs: increase inode cache size * libext2fs: improve caching for inodes --- lib/ext2fs/ext2fsP.h | 13 + lib/support/cache.h | 1 lib/support/iocache.h | 17 + debugfs/Makefile.in | 4 e2fsck/Makefile.in | 4 lib/ext2fs/Makefile.in | 4 lib/ext2fs/inode.c | 215 +++++++++++--- lib/ext2fs/io_manager.c | 3 lib/support/Makefile.in | 6 lib/support/cache.c | 16 + lib/support/iocache.c | 740 +++++++++++++++++++++++++++++++++++++++++++++++ misc/Makefile.in | 7 misc/fuse2fs.c | 75 +---- misc/fuse4fs.c | 73 ----- resize/Makefile.in | 4 tests/progs/Makefile.in | 4 16 files changed, 990 insertions(+), 196 deletions(-) create mode 100644 lib/support/iocache.h create mode 100644 lib/support/iocache.c
