Subject: mm: remove VM_FAULT_MINOR
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0e8fb9312fbaf1a687dd731b04d8ab3121c4ff5a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mm: remove VM_FAULT_MINOR

The define has a comment from Nick Piggin from 2007:

 /* For backwards compat. Remove me quickly. */

I guess 9 years should not be too hurried sense of 'quickly' even for
kernel measures.
