Subject: btrfs: remove shadowing variables in __btrfs_buffered_write
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f64c7b12f86c638f13e19de08eeb8cf888dff8f6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

btrfs: remove shadowing variables in __btrfs_buffered_write

There are lockstart and lockend defined in the function and not used
after their duplicate definition scope ends, it's safe to reuse them.
