From 59f2070acdb76bf078749a97f3cdfcb93a677c29 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 8 Nov 2024 09:15:19 -0700 Subject: [PATCH] xfs: flag as supporting FOP_UNCACHED Read side was already fully supported, for the write side all that's needed now is calling generic_uncached_write() when uncached writes have been submitted. With that, enable the use of RWF_UNCACHED with XFS by flagging support with FOP_UNCACHED.
