How do you think about to replace this wording by a variant like the following? Thus use the spin lock “cache->lock” to protect the access to the data structure member “cached” in the implementation of the function “btrfs_block_group_done”. Would you like to add the tag “Fixes” to the change description? Regards, Markus
