From 8b15575cae7a93a784c3005c42b069edd9ba64dd Mon Sep 17 00:00:00 2001 From: Sage Weil 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.
