Subject: fs/exec.c: do_execve_common(): use current_user()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd9d43f47d6944019918a801398c587ee86c4b52;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

fs/exec.c: do_execve_common(): use current_user()

Trivial cleanup.  do_execve_common() can use current_user() and avoid the
unnecessary "struct cred *cred" var.
