Subject: [PATCH v4 1/8] common/filter: add _filter_xfs_io_fiemap()
Date: Mon, 30 Sep 2019 14:15:46 -0700
Message-ID: <20190930211553.64208-2-ebiggers@kernel.org> (raw)
Message-ID: <20190930211546.DqF1dIQAeqC47zWNjk0ajNPSV_W_PvT3KUecB3sLQ1E@z> (raw)
In-Reply-To: <20190930211553.64208-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

Add _filter_xfs_io_fiemap() to clean up the output of
'xfs_io -c fiemap'.  This will be used by a function in common/verity.

 # We generate WARNINGs on purpose when applications mix buffered/mmap IO with
