From db02982a48257675f9b0a4d7e14ea144c32973fe Mon Sep 17 00:00:00 2001 From: Ross Zwisler Date: Wed, 11 Nov 2015 11:03:02 -0700 Subject: [PATCH] core.5: Add info about DAX coredump filtering flags Kernel 4.4 added two new core dump filtering flags, MMF_DUMP_DAX_PRIVATE and MMF_DUMP_DAX_SHARED. These flags allow us to explicitly filter DAX mappings. This is desirable because DAX mappings, like hugetlb mappings, have the potential to be very large.
