Subject: Btrfs: process mount options on mount -o remount,
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b288052e1779261ae80138074989ef50358c4e58;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: process mount options on mount -o remount,

Btrfs wasn't parsing any new mount options during remount, making it
difficult to set mount options on a root drive.
