From: Nikolay Borisov Date: Fri, 23 Feb 2018 11:45:28 +0000 (+0200) Subject: direct-io: Remove unused DIO_ASYNC_EXTEND flag X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c8f4c36f81623002165dce874fa60bb0c154b10e;p=openwrt%2Fstaging%2Fblogic.git direct-io: Remove unused DIO_ASYNC_EXTEND flag This flag was added by 6039257378e4 ("direct-io: add flag to allow aio writes beyond i_size") to support XFS. However, with the rework of XFS' DIO's path to use iomap in acdda3aae146 ("xfs: use iomap_dio_rw") it became redundant. So let's remove it.
