Subject: [PATCH 05/12] xfs: convert remaining kmem_free() to kfree()
Date: Tue, 16 Jan 2024 09:59:43 +1100	[thread overview]
Message-ID: <20240115230113.4080105-6-david@fromorbit.com> (raw)
In-Reply-To: <20240115230113.4080105-1-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

The remaining callers of kmem_free() are freeing heap memory, so
we can convert them directly to kfree() and get rid of kmem_free()
altogether.

This conversion was done with:

$ for f in `git grep -l kmem_free fs/xfs`; do
> sed -i s/kmem_free/kfree/ $f
> done
$
