Subject: btrfs: make FS_INFO ioctl available to anyone
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4ef90ff6198ac58d4c7dbbeae8cc7b24867d1ca;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

btrfs: make FS_INFO ioctl available to anyone

This ioctl provides basic info about the filesystem that can be obtained
in other ways (eg. sysfs), there's no reason to restrict it to
CAP_SYSADMIN.
