Subject: tests/btrfs.c: tweak magic constants to make the test more reliable
X-Git-Tag: v4.12~69
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=57888fa5f9969cb914bc322929551f7d52331ccc;p=strace

tests/btrfs.c: tweak magic constants to make the test more reliable

* tests/btrfs.c (btrfs_test_sync_ioctls): Change u64val
to 0xdeadbeefbadc0ded.
(btrfs_test_subvol_ioctls): Likewise.  Change bad_pointer
to make their lower 32-bit parts closer to -1U.
