From 4f6563677ae833baad8003e14353241bc25da4fc Mon Sep 17 00:00:00 2001 From: Benjamin Coddington Date: Thu, 22 Oct 2015 13:38:14 -0400 Subject: [PATCH] Move locks API users to locks_lock_inode_wait() Instead of having users check for FL_POSIX or FL_FLOCK to call the correct locks API function, use the check within locks_lock_inode_wait(). This allows for some later cleanup.
