From 97e5a6e6dc44b9ea660f85de084f6e38cb5cf39c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 18 Oct 2018 17:17:50 +1100 Subject: [PATCH] xfs: remove XFS_IO_INVALID The invalid state isn't any different from a hole, so merge the two states. Use the more descriptive hole name, but keep it as the first value of the enum to catch uninitialized fields.
