Subject: Remove unused variables from fs/proc/base.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=457c25107b83bc6456b3a18a25511418dc25da69;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Remove unused variables from fs/proc/base.c

When removing the explicit task_struct->pid usage I found that
proc_readfd_common() and proc_pident_readdir() get this field, but do not
use it at all.  So this cleanup is a cheap help with the task_struct->pid
isolation.
