From a5c43dae7ae38c2a6b3e9a819bcf45f010bf6a4a Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 8 May 2007 00:28:47 -0700 Subject: Fix race between cat /proc/slab_allocators and rmmod Same story as with cat /proc/*/wchan race vs rmmod race, only /proc/slab_allocators want more info than just symbol name.
