From 5bd5e8d891c1fd2d966a7e2c26f0452d22410683 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Tue, 3 Apr 2018 16:54:10 -0400 Subject: dm: remove fmode_t argument from .prepare_ioctl hook Use the fmode_t that is passed to dm_blk_ioctl() rather than inconsistently (varies across targets) drop it on the floor by overriding it with the fmode_t stored in 'struct dm_dev'. All the persistent reservation functions weren't using the fmode_t they got back from .prepare_ioctl so remove them.
