From a12af1ebe675e85831fde3c4d0908fc3b0908b7a Mon Sep 17 00:00:00 2001 From: Abhijith Das Date: Mon, 1 Jun 2009 12:30:03 -0500 Subject: [PATCH] GFS2: smbd proccess hangs with flock() call. GFS2 currently does not support mandatory flocks. An flock() call with LOCK_MAND triggers unexpected behavior because gfs2 is not checking for this lock type. This patch corrects that.
