dm: remove dm_request loop
Remove queue_io return value and a loop in dm_request.
IO may be submitted to a worker thread with queue_io(). queue_io() sets
DMF_QUEUE_IO_TO_THREAD so that all further IO is queued for the thread. When
the thread finishes its work, it clears DMF_QUEUE_IO_TO_THREAD and from this
point on, requests are submitted from dm_request again. This will be used
for processing barriers.
Remove the loop in dm_request. queue_io() can submit I/Os to the worker thread
even if DMF_QUEUE_IO_TO_THREAD was not set.

indicating connect failure once from nes_connect() and the other when
the rexmit retries expires.
The other issue is skb->users which we are incrementing before calling
nes_nic_cm_xmit() which calls dev_queue_xmit() but in case of failure
we are decrementing the skb->users at the same time putting the skb on
the rexmit path. Even if dev_queue_xmit() fails, the skb->users is
decremented already. We are removing the decrement of skb->users in
case of failure from both schedule_nes_timer() as well as from
nes_cm_timer_tick().

Otherwise, when we run sync() or fsync() and we need to write out a

posix-timers: fix RLIMIT_CPU && setitimer(CPUCLOCK_PROF)
update_rlimit_cpu() tries to optimize out set_process_cpu_timer() in case

uses cputime_lt() instead of cputime_gt().
Test case:
int main(void)

};
assert(!setitimer(ITIMER_PROF, &it, NULL));

copy_signal() copies signal->rlim, but RLIMIT_CPU is "lost". Because
posix_cpu_timers_init_group() sets cputime_expires.prof_exp = 0 and thus
fastpath_timer_check() returns false unless we have other expired cpu timers.
Change copy_signal() to set cputime_expires.prof_exp if we have RLIMIT_CPU.
Also, set cputimer.running = 1 in that case. This is not strictly necessary,

xsysace: Fix dereferencing of cf_id after hd_driveid removal
Commit
4aaf2fec718f6fbf38668edf733a0ab09a49cab1 (xsysace: make it
'struct hd_driveid'-free) converted the cf_id member of 'struct
ace_device' from a 'struct hd_driveid' to a u16 array. However,
references to the base of the structure were still using the '&'
operator. When the address was used with the ata_id_u32() macro, the
compiler used the size of the entire array instead of sizeof(u16) to
calculate the offset from the base address.
This patch removes the use of the '&' operator from all references of
cf_id to fix the bug and remove future confusion.

ide: Fix host drivers that need IRQF_SHARED
commit
255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to
specify IRQ flags") added irq_flags fields to struct ide_port_info and struct
ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while
init_irq() passes ide_host.irq_flags to request_irq().
Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM):
| Uniform Multi-Platform E-IDE driver
| ide: Falcon IDE controller
| Probing IDE interface ide0...
| hda: Sarge m68k, ATA DISK drive
| init_irq: sa = 0
| ide0: disabled, unable to get IRQ 15
| ide0: failed to initialize IDE interface
| ide0: disabling port
Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in
ide_host_alloc().
This bug probably affects the following IDE host drivers:
- buddha
- delkin_cb
- falconide
- gayle
- ide-cs
- macide
- q40ide
- scc_pata
- sgiioc4
