From 0b3dcd131d5b02ab8e038e55fef243e51b06fe96 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Thu, 11 Feb 2021 16:14:05 +0800 Subject: [PATCH] btrfs: fix comment for btrfs ordered extent flag bits There is small error in comment about BTRFS_ORDERED_* flags, added in commit 3c198fe06449 ("btrfs: rework the order of btrfs_ordered_extent::flags") but the fixup did not get merged in time. The 4 types are for ordered extent itself, not for direct io. Only 3 types support direct io, REGULAR/NOCOW/PREALLOC. Fix the comment to reflect that.
