Qu Wenruo 3818aea275 btrfs: Add noinode_cache mount option ... Add noinode_cache mount option for btrfs. Since inode map cache involves all the btrfs_find_free_ino/return_ino things and if just trigger the mount_opt, an inode number get from inode map cache will not returned to inode map cache. To keep the find and return inode both in the same behavior, a new bit in mount_opt, CHANGE_INODE_CACHE, is introduced for this idea. CHANGE_INODE_CACHE is set/cleared in remounting, and the original INODE_MAP_CACHE is set/cleared according to CHANGE_INODE_CACHE after a success transaction. Since find/return inode is all done between btrfs_start_transaction and btrfs_commit_transaction, this will keep consistent behavior. Also noinode_cache mount option will not stop the caching_kthread.
