Subject: reiserfs_permission() doesn't need to bail out in RCU mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d29b5a2ed7eb8862c9b66daf475f3e4c1a40299;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

reiserfs_permission() doesn't need to bail out in RCU mode

nothing blocking other than generic_permission() (and
check_acl callback does bail out in RCU mode).
