From 675a4fc8f3149e93f35fb5739fd8d4764206ba0b Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 15 Dec 2020 12:00:26 -0500 Subject: [PATCH] btrfs: tests: initialize test inodes location I noticed that sometimes the module failed to load because the self tests failed like this: BTRFS: selftest: fs/btrfs/tests/inode-tests.c:963 miscount, wanted 1, got 0 This turned out to be because sometimes the btrfs ino would be the btree inode number, and thus we'd skip calling the set extent delalloc bit helper, and thus not adjust ->outstanding_extents. Fix this by making sure we initialize test inodes with a valid inode number so that we don't get random failures during self tests.
