When function tracer has a pid filter, it adds a probe to sched_switch
to track if current task can be ignored. The probe checks the
ftrace_ignore_pid from current tr to filter tasks. But it misses to
delete the probe when removing an instance so that it can cause a crash
due to the invalid tr

remove this calculation
- offset = sector & (SECTORS_PER_PAGE - 1) << SECTOR_SHIFT;
and pass 0 to zram_bvec_rw()

Hello,
I'll fork it into a separate thread and Cc more MM people.
sorry for top-posting.
Minchan reported that doing copy_page() on a kmalloc(PAGE_SIZE) page
with DEBUG_SLAB enabled can cause a memory corruption (See below or
lkml.kernel.org/r/1492042622-12074-2-git-send-email-minc...@kernel.org

With vfio_lock_acct() testing the locked memory limit under mmap_sem,
it's redundant to do it here for a single page. We can also reorder
our tests such that we can avoid testing for reserved pages if we're
not doing accounting, and test the process CAP_IPC_LOCK only if we
are doing accounting.

If the mmap_sem is contented then the vfio type1 IOMMU backend will
defer locked page accounting updates to a workqueue task. This has a
few problems and depending on which side the user tries to play, they
might be over-penalized for unmaps that haven't yet been accounted or
race the workqueue

v4: vfio_lock_acct() should not fail due to RLIMIT_MEMLOCK if task
has CAP_IPC_LOCK capability. Introduced 2nd patch to remove
redundancy from vfio_pin_page_external() and fix return value.
Please re-review. Thanks!

Hi Joonsoo,
I reviewed this patch and overall, looks great! Thanks.
However, as you know, recently, zram had lots of clean up so
this patchset should be rebased on it massively.
Sorry for the inconvenience.
And there are some minor in below. I hope you handle them in
next submit, please.
