Subject: proc: kill the extra proc_readfd_common()->dir_emit_dots()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5a1955e0c2d4d325fabdf6b09aa3f9d33e78a10;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

proc: kill the extra proc_readfd_common()->dir_emit_dots()

proc_readfd_common() does dir_emit_dots() twice in a row,
we need to do this only once.
