e24263935c [ 3.309944] kernel BUG at fs/inode.c:1561!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git work.mkdir
commit e24263935c81b07518ce392fd8b276d5e9f081da
Author: Miklos Szeredi <mszeredi(a)redhat.com>
AuthorDate: Fri Jul 6 22:45:21 2018 +0200
Commit: Al Viro <viro(a)zeniv.linux.org.uk>
CommitDate: Thu Jul 19 18:58:14 2018 -0400
vfs: don't evict uninitialized inode
iput() ends up calling ->evict() on new inode, which is not yet initialized
by owning fs. So use destroy_inode() instead.
Add to sb->s_inodes list only if inode is not in I_CREATING state (meaning
that it wasn't allocated with new_inode(), which already does the
insertion).

mm: make zone_reclaim_stat updates thread-safe
lru_lock needs to be held to update the zone_reclaim_stat statistics.
Similar to the previous patch, this requirement again arises fairly
naturally because callers are holding lru_lock already.
In preparation for allowing concurrent adds and removes from the LRU,
however, make concurrent updates to these statistics safe without
lru_lock. The lock continues to be held until later in the series, when
it is replaced with a rwlock that also disables preemption, maintaining
the assumption in the comment above __update_page_reclaim_stat, which is
introduced here.
Use a combination of per-cpu counters and atomics.

PCI: endpoint: Create configfs entry for each pci_epf_device_id table entry
In order to be able to provide correct driver_data for pci_epf device,
a separate configfs entry for each pci_epf_device_id table entry in
pci_epf_driver is required.
Add support to create configfs entry for each pci_epf_device_id
table entry here.

[PATCH] blk-mq: fail the request in case issue failure
by Ming Lei
Inside blk_mq_try_issue_list_directly(), if the request is issued as
failed, we shouldn't try to do it again, otherwise the warning in
blk_mq_start_request() will be triggered. This change is aligned to
behaviour of other ways of request issue & dispatch.
Fixes: 6ce3dd6eec1 ("blk-mq: issue directly if hw queue isn't busy in case of 'none'")

[lkp-robot] [tracing] ecadccb31b: kernel_selftests.ftrace.ftracetest.fail
by kernel test robot
FYI, we noticed the following commit (built with gcc-7):
commit: ecadccb31b8f1516dd045cc64fc7bc7a2d72947f ("[PATCH 1/2] tracing: kprobes: Prohibit probing on notrace functions")
url: https://github.com/0day-ci/linux/commits/Francis-Deslauriers/tracing-kpro...
in testcase: kernel_selftests
with following parameters:
group: kselftests-01
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: 8 threads Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz with 8G memory

rcutorture: Add forward-progress tests for RCU grace periods
This commit adds a kthread that loops going into and out of RCU
read-side critical sections, but also including a cond_resched(),
optionally guarded by a check of need_resched(), in that same loop.
This commit relies solely on rcu_torture_writer() progress to judge
the forward progress of grace periods.

x86: Remap the IRQ stack so it has guard pages
The IRQ stack lives in percpu space, so an IRQ handler that
overflows it could overwrite other data structures. Use vmap() to
remap the IRQ stack so that it will have the usual guard pages that
vmap/vmalloc allocations have.
With this patch, the kernel will panic immediately on an IRQ stack
overflow.
Known issues:
- The code needs to be moved somewhere sensible.
- The handle_stack_overflow() code should learn that there is more
than one stack that could overflow.
