From c6f990d1ff8e4e53b12f4175eb7d7ea710c3ca73 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 27 Jan 2011 13:23:28 +1100 Subject: [PATCH] xfs: handle CIl transaction commit failures correctly Failure to commit a transaction into the CIL is not handled correctly. This currently can only happen when racing with a shutdown and requires an explicit shutdown check, so it rare and can be avoided. Remove the shutdown check and make the CIL commit a void function to indicate it will always succeed, thereby removing the incorrectly handled failure case.
