Subject: Btrfs: Fix mount -o max_inline=0
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=15ada040d7cd68d7853938a92b116292cc16a2f3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: Fix mount -o max_inline=0

max_inline=0 used to force the max_inline size to one sector instead.  Now
it properly disables inline data items, while still being able to read
any that happen to exist on disk.
