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 (?)

Hello, I''m seeing a lot of warnings in dmesg with a BTRFS filesystem.

Hi, We have file readahead to do asyn file read, but has no metadata readahead. For a list of files, their metadata is stored in fragmented disk space and metadata read is a sync operation, which impacts the efficiency of readahead much. The patches try to add meatadata readahead for btrfs. In btrfs, metadata is stored in btree_inode. Ideally, if we could hook the inode to a fd so we could use

If we have particularly full nodes, we could call btrfs_node_blockptr up to 32 times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the extent buffer while we look for readahead targets.

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 th...

An ioctl is needed to set compress flag (i.e. clear BTRFS_INODE_NOCOMPRESS flag) on per file basis. This patch adds that. Introduces a generic function to be used by subsequent patches.
