From cb0b476ab12ca3bd9dd9122047660f3a73e8d647 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sat, 17 Mar 2018 16:26:56 +0100 Subject: fs/quota: add kernel_quotactl() helper; remove in-kernel call to syscall Using the fs-internal kernel_quotactl() helper allows us to get rid of the fs-internal call to the sys_quotactl() syscall. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined.
