Subject: Btrfs: fix wrong argument for btrfs_lookup_ordered_range
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a9239acb465df1f6aab379c77befd5cde98c9df;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: fix wrong argument for btrfs_lookup_ordered_range

Commit Btrfs: btrfs_page_mkwrite: Reserve space in sectorsized units"
(d0b7da88) did this, but btrfs_lookup_ordered_range expects a 'length'
rather than a 'page_end'.
