[PATCH v2 0/5] add new ioctls to do metadata readahead in btrfs

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

[PATCH v2 1/5] add metadata_incore ioctl in vfs

Add an ioctl to dump filesystem's metadata in memory in vfs. Userspace collects such info and uses it to do metadata readahead. Filesystem can hook to super_operations.metadata_incore to get metadata in specific approach. Next patch will give an example how to implement .metadata_incore in btrfs.

[PATCH v2 2/5] implement metadata_incore in btrfs

Implement btrfs specific .metadata_incore. In btrfs, all metadata pages are in a special btree_inode, we take pages from it. we only account updated and referenced pages here. Say we collect metadata info in one boot, do metadata readahead in next boot and we might collect metadata again. The

[PATCH v2 5/5] validate extent_buffer if it's readahead in btrfs

do validation for extent_buffer if it's skipped before With metadata readahead, we slightly change the behavior. Before it, we allocate an extent_buffer (so set page-private), do metadata read and btree_readpage_end_io_hook() will do validation. After it, we directly do metadata readahead, and
