Date: Thu, 14 Apr 2022 10:22:58 -0400 From: Eric Whitney <enwlinux@...il.com> To: fstests@...r.kernel.org Cc: linux-ext4@...r.kernel.org, Eric Whitney <enwlinux@...il.com> Subject: [PATCH] common/filter: extend _filter_xfs_io to match -nan When run on ext4 with sufficiently fast x86_64 hardware, generic/130 sometimes fails because xfs_io can report rate values as -nan: 0.000000 bytes, 0 ops; 0.0000 sec (-nan bytes/sec and -nan ops/sec) _filter_xfs_io matches the strings 'inf' or 'nan', but not '-nan'. In that case it fails to convert the actual output to a normalized form matching generic/130's golden output. Extend the regular expression used to match xfs_io's output to fix this.
