Subject: [PATCH 1/3] nfs: Drop pointless check from nfs_commit_release_pages()
Date: Thu, 13 Jun 2024 10:28:17 +0200 [thread overview]
Message-ID: <20240613082821.849-1-jack@suse.cz> (raw)
In-Reply-To: <20240612153022.25454-1-jack@suse.cz>
nfss->writeback is updated only when we are ending page writeback and at
that moment we also clear nfss->write_congested. So there's no point in
rechecking congestion state in nfs_commit_release_pages(). Drop the
pointless check.
