Subject: [PATCH 10/14] bdi: remove BDI_CAP_SYNCHRONOUS_IO
Date: Fri, 24 Jul 2020 09:33:09 +0200	[thread overview]
Message-ID: <20200724073313.138789-11-hch@lst.de> (raw)
In-Reply-To: <20200724073313.138789-1-hch@lst.de>

BDI_CAP_SYNCHRONOUS_IO is only checked in the swap code, and used to
decided if ->rw_page can be used on a block device.  Just check up for
the method instead.  The only complication is that zram needs a second
set of block_device_operations as it can switch between modes that
actually support ->rw_page and those who don't.
