Subject: Btrfs: Remove bogus max_sector warnings from the extent_io code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=41471e8341a6b476bcd8ecc765a8b297c22a74f9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: Remove bogus max_sector warnings from the extent_io code

It was testing the bio before doing logical->physical mapping, so the
test was always wrong.
