Date: Thu, 8 May 2025 15:42:44 +0800 [thread overview]
Message-ID: <202505081540.3f2a6418-lkp@intel.com> (raw)
Hello,
kernel test robot noticed "Oops:general_protection_fault,probably_for_non-canonical_address#:#[##]SMP_KASAN_NOPTI" on:
commit: 25efcff06654aa283be379420e8b1f8d344c2f78 ("btrfs_get_tree_subvol(): switch from fc_mount() to vfs_create_mount()")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
[test failed on linux-next/master 08710e696081d58163c8078e0e096be6d35c5fad]
in testcase: xfstests
version: xfstests-x86_64-8467552f-1_20241215
with following parameters:
disk: 4HDD
fs: xfs
test: xfs-scratch-reflink-25
NOTE
sorry if above xfs-related tests cause confusion. as below dmesg, the issue
happens for a btrfs partition (label LKP-ROOTFS, which is mounted before
testing for various purposes in our bot process)
config: x86_64-rhel-9.4-func
compiler: gcc-12
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory
(please refer to attached dmesg/kmsg for entire log/backtrace)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
