[PATCH 1/3] kvfree(): Fix misleading comment.

From: Andrey Ryabinin
Date: Fri Sep 14 2018 - 09:05:09 EST


vfree() might sleep if called not in interrupt context.
So does kvfree() too. Fix misleading kvfree()'s comment about
allowed context.

Fixes: 04b8e946075d ("mm/util.c: improve kvfree() kerneldoc")
