The patch titled
Subject: slab: make GFP_SLAB_BUG_MASK information more human readable
has been removed from the -mm tree. Its filename was
slab-make-gfp_slab_bug_mask-information-more-human-readable.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Michal Hocko <mhocko@xxxxxxxx>
Subject: slab: make GFP_SLAB_BUG_MASK information more human readable
printk offers %pGg for quite some time so let's use it to get a human
readable list of invalid flags.
The original output would be
[ 429.191962] gfp: 2
after the change
[ 429.191962] Unexpected gfp: 0x2 (__GFP_HIGHMEM)
