From 48fa1db87f730da1aed2d3df0cc8c33c7c133b4b Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 7 May 2018 09:20:17 -0700 Subject: [PATCH] xfs: pass full xfs_dqblk to repair during quotacheck It's a bit dicey to pass in the smaller xfs_disk_dquot and then cast it to something larger; pass in the full xfs_dqblk so we know the caller has sent us the right thing. Rename the function to xfs_dqblk_repair for clarity. Signed-off-by: Eric Sandeen Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
