From 94f3cad555d66048906deade06a764f7ea2c6e4d Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Tue, 9 Sep 2014 11:57:52 +1000 Subject: [PATCH] xfs: check resblks before calling xfs_dir_canenter Move the resblks test out of the xfs_dir_canenter, and into the caller. This makes a little more sense on the face of it; xfs_dir_canenter immediately returns if resblks !=0; and given some of the comments preceding the calls: * Check for ability to enter directory entry, if no space reserved. even more so. It also facilitates the next patch.
