From d2db6cfbc5b7abbfa5dc86a28ceebc38e487666d Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Wed, 19 Jun 2019 13:05:50 +0100 Subject: [PATCH] Btrfs: add missing inode version, ctime and mtime updates when punching hole commit 179006688a7e888cbff39577189f2e034786d06a upstream. If the range for which we are punching a hole covers only part of a page, we end up updating the inode item but we skip the update of the inode's iversion, mtime and ctime. Fix that by ensuring we update those properties of the inode. A patch for fstests test case generic/059 that tests this as been sent along with this fix.
