Subject: [PATCH 4/4] fs: clean up generic_update_time a bit
Date: Wed, 25 Mar 2020 13:28:25 +0100
Message-ID: <20200325122825.1086872-5-hch@lst.de> (raw)
In-Reply-To: <20200325122825.1086872-1-hch@lst.de>

There is no need both the sync and iflag variables - just use dirty as
the indicator for which flag to pass to __mark_inode_dirty, as there
is no point in passing both flags - __mark_inode_dirty will immediately
clear I_DIRTY_TIME if I_DIRTY_SYNC is set.
