Date: Sun, 19 May 2019 19:34:47 +0000 [thread overview]
Message-ID: <bug-203647-206035@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=203647
Bug ID: 203647
Summary: Locking API testsuite fails "mixed
read-lock/lock-write ABBA" rlock on kernels >=4.14.x
Product: Platform Specific/Hardware
Version: 2.5
Kernel Version: 5.1.3
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: PPC-64
Assignee: platform_ppc-64@kernel-bugs.osdl.org
Reporter: erhard_f@mailbox.org
Regression: No
Created attachment 282831

dmesg (5.1.3, G5 11,2)
Probably this test fails on ppc64 since it is around. Kernel 4.9.x passes all
tests, since it does not seem to contain "mixed read-lock/lock-write ABBA".
Machine is a PowerMac G5 11,2 running Gentoo Linux ppc64, Big Endian, 4 KiB
pagesize.
