Subject: Btrfs: update to use fs_state bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d763448286377b8a0e3f179372e9e292bef3c337;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: update to use fs_state bit

Now that we use bit operation to check fs_state, update
btrfs_free_fs_root()'s checker, otherwise we get back to
memory leak case.
