In that case there is no work -to do to remove it, and in fact xfs_da_shrink_inode will lead to an oops -if we try. - -This also seems to fix a flaw where the original error from -xfs_attr3_leaf_create gets overwritten in the cleanup case, and it -removes a pointless assignment to bp which isn't used after this. - -Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=199969 -Reported-by: Xu, Wen <wen.xu@gatech.edu> -Tested-by: Xu, Wen <wen.xu@gatech.edu> -Signed-off-by: Eric Sandeen <sandeen@redhat.com> -Reviewed-by: Darrick J.
