The lo_ctl_mutex is held for running all ioctl handlers, and
in some ioctl handlers, ioctl_by_bdev(BLKRRPART) is called for
rereading partitions, which requires bd_mutex.
So it is easy to cause failure because trylock(bd_mutex) may
fail inside blkdev_reread_part(), and follows the
This patch exports blkdev_reread_part() for block drivers, also
introduce __blkdev_reread_part(), a lockless version.
For some drivers, such as loop, a reread of partitions can be run
from the release path, and bd_mutex may already be held prior to
calling ioctl_by_bdev(bdev, BLKRRPART, 0), so int
With the mutex_trylock bit gone from blkdev_reread_part(), the retry logic
in dasd_scan_partitions() shouldn't be necessary.

For loop, the root cause is one ABBA and one AA lock dependency
issue, and the two are fixed by patch 2 and patch 3 each.
Another reason is from the trylock in blkdev_reread_part(), which
may cause partition scanning failure too sometimes when another task
is holding the bd_mutex. In the discussio

Currently, userspace has no way to know which subvolume is mounted. But,
now that we're guaranteed to have a meaningful root dentry, we can just

Hi Jens,
In blk_mq_map_swqueue(), all the blk_mq_hw_ctx's nr_ctx are set
to zero, and then each blk_mq_ctx's index_hw is set to nr_ctx.
I think the index_hw means the index of the hardware queue that map
to this software queue, so maybe index_hw should be set to
blk_mq_hw_ctx's queue_num.

Yeah, we used to do that because vmalloc would BUG rather than
returning NULL.
But you're already CAP_SYS_MODULE in this path, which kind of makes it
hard to care very much ab
Yes; reverting the patch does fix the problem.

This change makes it so that instead of using smp_wmb/rmb which varies
depending on the kernel configuration we can can use dma_wmb/rmb which for
most architectures should be equal to or slightly more strict than
smp_wmb/rmb.
The advantage to this is that these barriers are available to uniprocess

Currently, the PMU interface allows reading only one counter at a time.
But some PMUs like the 24x7 counters in Power, support reading several
counters at once. To leveage this functionality, extend the transaction
interface to support a "transaction type".
The first type, PERF_PMU_TXN_ADD, refers
Define a new PERF_PMU_TXN_READ interface to read a group of counters
at once. Note that we use this interface with all PMUs.
PMUs that implement this interface will queue the counters to be read
in ->read() and read them all at once in ->commit_txn().
PMUs that don't implement PERF_PMU_TXN_READ w
Please disregard this, I messed up on the indexing. Will resubmit after fixing.

The 24x7 counters in Powerpc allow monitoring a large number of counters
simultaneously. They also allow reading several counters in a single
HCALL so we can get a more consistent snapshot of the system.
Use the PMU's transaction interface to monitor and read several event
counters at once. The id
perf_event_read_value() is mostly computing the event count and enabled/

perf_event_read_value() to perf_event_compute_values().
Changelog[v2]
Export symbol perf_event_read() since x86/kvm needs it now.

Unlike normal hardware PMCs, the 24x7 counters[1] in Power8 are stored in
memory and accessed via a hypervisor call (HCALL). A major aspect of the
HCALL is that it allows retireving _SEVERAL_ counters at once (unlike
regular PMCs, which are read one at a time). By reading several counters
at once,
