Subject: [PATCH v8 RESEND 6/8] nfsd: move nfsd4_change_attribute to nfsfh.c
Date: Tue, 24 Jan 2023 14:30:23 -0500	[thread overview]
Message-ID: <20230124193025.185781-7-jlayton@kernel.org> (raw)
In-Reply-To: <20230124193025.185781-1-jlayton@kernel.org>

This is a pretty big function for inlining. Move it to being
non-inlined.

Acked-by: Chuck Lever <chuck.lever@oracle.com>
