Subject: include/linux/gfp.h: convert BUG_ON() into VM_BUG_ON()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=82d4b5779a75887750748609f3415f01c1bb9f81;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

include/linux/gfp.h: convert BUG_ON() into VM_BUG_ON()

VM_BUG_ON() if effectively a BUG_ON() undef #ifdef CONFIG_DEBUG_VM.  That
is exactly what we have here now, and two different folks have suggested
doing it this way.
