Subject: [f2fs-dev] [PATCH v2 10/12] gfs2: don't worry about I_DIRTY_TIME in gfs2_fsync()
Date: Fri, 8 Jan 2021 23:59:01 -0800 [thread overview]
Message-ID: <20210109075903.208222-11-ebiggers@kernel.org> (raw)
In-Reply-To: <20210109075903.208222-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
The I_DIRTY_TIME flag is primary used within the VFS, and there's no
reason for ->fsync() implementations to do anything with it. This is
because when !datasync, the VFS will expire dirty timestamps before
calling ->fsync(). (See vfs_fsync_range().) This turns I_DIRTY_TIME
into I_DIRTY_SYNC.
Therefore, change gfs2_fsync() to not check for I_DIRTY_TIME.
