Subject: [PATCH 1/2] fs: add FMODE_DIO_PARALLEL_WRITE flag
Date: Wed, 12 Apr 2023 15:40:57 +0200 [thread overview]
Message-ID: <20230412134057.381941-1-bschubert@ddn.com> (raw)
In-Reply-To: <20230307172015.54911-2-axboe@kernel.dk>
Miklos, Jens,
could we please also set this flag for fuse?
Thanks,
Bernd
fuse: Set FMODE_DIO_PARALLEL_WRITE flag
From: Bernd Schubert <bschubert@ddn.com>
Fuse can also do parallel DIO writes, if userspace has enabled it.
