Zdenek Kabelac b1bcff7424 Critical section ... New strategy for memory locking to decrease the number of call to to un/lock memory when processing critical lvm functions. Introducing functions for critical section. Inside the critical section - memory is always locked. When leaving the critical section, the memory stays locked until memlock_unlock() is called - this happens with sync_local_dev_names() and sync_dev_names() function call. memlock_reset() is needed to reset locking numbers after fork (polldaemon). The patch itself is mostly rename: memlock_inc -> critical_section_inc memlock_dec -> critical_section_dec memlock -> critical_section Daemons (clmvd, dmevent) are using memlock_daemon_inc&dec (mlockall()) thus they will never release or relock memory they've already locked memory. Macros sync_local_dev_names() and sync_dev_names() are functions. It's better for debugging - and also we do not need to add memlock.h to locking.h header (for memlock_unlock() prototyp).		2011-02-18 14:16:11 +00:00
