[RFC PATCH V2] Btrfs: introduce extent buffer cache for each i-node
This patch introduce extent buffer cache for every i-node. By this
way, we can save the search time and reduce the lock contention of the root
because we needn''t search the item from the root of b+ tree.
Implementation:
- add two pointers of extent buffer into btrfs_inode struct, one for
nodes/leaves of fs/file tree, the other for nodes/leaves of the log tree.
- add a variant to tell us that it is still in the b+ tree.
- When we want to search fs/file trees or the relative log trees, we will
try to search the cached extent buffer at first, if we can not find t...

WARNING: at fs/btrfs/inode.c:2198 btrfs_orphan_commit_root+0xa8/0xc0
Hello,
I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using
the 3.1 kernel, I found a patch for these warnings (

<http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch
has already been included in 3.1. Are there any other patches I can try?

[PATCH] Btrfs: fix an oops when deleting snapshots
...lt;ffffffffa054f7b9>] btrfs_orphan_add+0x179/0x1a0 [btrfs]
When it comes to btrfs_lookup_dentry, we may set a snapshot''s inode->i_ino
to BTRFS_EMPTY_SUBVOL_DIR_OBJECTID instead of BTRFS_FIRST_FREE_OBJECTID,
while the snapshot''s location.objectid remains unchanged.
However, btrfs_ino() does not take this into account, and returns a wrong ino,
and causes the oops.

Ceph on btrfs 3.4rc
After running ceph on XFS for some time, I decided to try btrfs again.
Performance with the current "for-linux-min" branch and big metadata
is much better. The only problem (?) I''m still seeing is a warning
that seems to occur from time to time:

[PATCH 1/2 v3] Btrfs: use flag EXTENT_DEFRAG for snapshot-aware defrag
We''re going to use this flag EXTENT_DEFRAG to indicate which range
belongs to defragment so that we can implement snapshow-aware defrag:
We set the EXTENT_DEFRAG flag when dirtying the extents that need
defragmented, so later on writeback thread can differentiate between
normal writeback and writeback started by defragmentation.
This patch is used for the latter one.
