Subject: 4.19.5 and later has tons of false messages "BUG: non-zero pgtables_bytes on freeing mm: -16384"
Date: Thu, 27 Dec 2018 10:13:01 +0100 [thread overview]
Message-ID: <4e58571e-1991-4a70-7012-ff9dd76afee3@de.ibm.com> (raw)
Martin,
Right now you get a message
"BUG: non-zero pgtables_bytes on freeing mm: -16384"
for EVERY process that exits in 4.19.5 and later.
bisect points to
commit 4136161d676a93fc8df6bdb80d720c15522d6c24
Author: Martin Schwidefsky <schwidefsky@de.ibm.com>

s390/mm: fix mis-accounting of pgtable_bytes
[ Upstream commit e12e4044aede97974f2222eb7f0ed726a5179a32 ]
Turns out that this patch requires several dependencies so the autoselection of this
patch was missing that.
Can we either revert this patch or add the dependencies?
Christian
