Getting these stubs upstream prior to the merge window will make it a bit easier for subsystems to make the necessary changes (non-trivial, in Ceph's case), test in linux-next without conflicts, and avoid worrying about the order in which things are pulled for 2.6.37. Would you mind taking the patch below now? Thanks! sage --- From: Sage Weil <sage@...dream.net> Date: Tue, 21 Sep 2010 14:35:37 -0700 Subject: [PATCH] fs: {lock,unlock}_flocks() stubs to prepare for BKL removal The lock structs are currently protected by the BKL, but are accessed by code in fs/locks.c and misc file system and DLM code. These stubs will allow all users to switch to the new interface before the implementation is changed to a spinlock.
