Nikolay Borisov a5ed45f822 btrfs: Convert fs_info->free_chunk_space to atomic64_t ... The ->free_chunk_space variable is used to track the unallocated space and access to it is protected by a spinlock, which is not used for anything else. Make the code a bit self-explanatory by switching the variable to an atomic64_t type and kill the spinlock. Signed-off-by: Nikolay Borisov <nborisov@suse.com> [ not a performance critical code, use of atomic type is ok ] Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>		2017-06-19 18:25:58 +02:00
