[PATCH 20/42] bfs: Sync and invalidate metadata buffers from bfs_evict_inode()

[Jan Kara <jack@suse.cz>]

There are only very few filesystems using generic metadata buffer head
tracking and everybody is paying the overhead. When we remove this
tracking for inode reclaim code .evict will start to see inodes with
metadata buffers attached so write them out and prune them.
