Hi, In btrfs, inode number is increased each time a new file or directory is made. Therefore, if the making deletion of the file is repeated, value of ''i_ino'' increases rapidly. For example, inode number changes as follows. $ touch foo $ ls -i foo 266 foo $ rm foo $ touch bar $ ls -i bar 267 bar $ And then, length of ''i_ino'' and

...layed item routines. Li, one thing I haven''t done yet is a lot of benchmarking on the performance hit from waiting for the cache to fill on large existing filesystems. Was there any particular reason you didn''t setup the caching to pre-cache the from root->highest_objectid to BTRFS_LAST_FREE_OBJECTID? diffstat for my current tree: -chris ]# git diff --stat v2.6.39...HEAD fs/btrfs/Makefile | 2 +- fs/btrfs/acl.c | 2 +- fs/btrfs/btrfs_inode.h | 14 + fs/btrfs/compression.c | 47 +- fs/btrfs/compression.h | 2 +- fs/btrfs/ctree.c |...

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply
