[PATCH v3 0/2] Use blocked_lock_lock only to protect blocked_hash
From: Daniel Wagner
Date: Fri Mar 06 2015 - 02:53:42 EST
Hi,
Finally, I got a bigger machine and did a quick test round. I expected
to see some improvements but the resutls do not show any real gain. So
they are merely refactoring patches.

v3:
- added missing !IS_OFDLCK
- removed unnecessary locking protecting fl_list by flock_lock_lglock
v2:
- added a few lockdep assertion
- dropped spinlock conversion
v1:
- rebased on v3.19-8975-g3d88348
- splittet into smaller pieces
- fixed a wrong usage of __locks_insert/delete_block() and it's posix version
- added seqfile helpers to avoid ugly open coded version
