From: Hugh Dickins Date: Mon, 16 Jul 2007 06:38:23 +0000 (-0700) Subject: mspec_mmap: don't set VM_LOCKED X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5dc4ac6324094cd52dc77ddf88296a94b90bbafc;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mspec_mmap: don't set VM_LOCKED mspec_mmap was setting VM_LOCKED (without adjusting locked_vm): don't do that, it serves no purpose in 2.6, other than to mess up the locked_vm accounting - mspec's pages won't get reclaimed anyway. Thanks to Dmitry Monakhov for raising the issue.
