Following this mail is a series of patches to fix a number of FS-Cache issues, including a number of oopses. The patches can also be found at: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=fscache The patches are as follows: (1) Don't put spin_lock() in a while-condition as spin_lock() may be wrapped with do {} while(0) (cleanup). (2) Name i_mutex lock classes rather than using numbers in CacheFiles (cleanup). (3) Don't sleep in page release if __GFP_FS is not set (deadlock vs ext4). (4) Uninline fscache_object_init() (cleanup). (5) Wrap checks on object state (cleanup). (6) Provide a system wait_on_atomic_t() and wake_up_atomic_t() (enhancement). (7) Simplify the object state machine (need #4 and #5). (8) Simplify cookie retention by objects (oops fix, need #6 and #7).
