ext4: remove i_mutex lock in ext4_evict_inode to fix lockdep complaining

The i_mutex lock and flush_completed_IO() added by commit 2581fdc810
in ext4_evict_inode() causes lockdep complaining about potential
deadlock in several places.  In most/all of these LOCKDEP complaints
it looks like it's a false positive, since many of the potential
circular locking cases can't take place by the time the
ext4_evict_inode() is called; but since at the very least it may mask
real problems, we need to address this.

This change removes the flush_completed_IO() and i_mutex lock in
ext4_evict_inode().  Instead, we take a different approach to resolve
the software lockup that commit 2581fdc810 intends to fix.  Rather
than having ext4-dio-unwritten thread wait for grabing the i_mutex
lock of an inode, we use mutex_trylock() instead, and simply requeue
the work item if we fail to grab the inode's i_mutex lock.

This should speed up work queue processing in general and also
prevents the following deadlock scenario: During page fault,
shrink_icache_memory is called that in turn evicts another inode B.
Inode B has some pending io_end work so it calls ext4_ioend_wait()
that waits for inode B's i_ioend_count to become zero.  However, inode
B's ioend work was queued behind some of inode A's ioend work on the
same cpu's ext4-dio-unwritten workqueue.  As the ext4-dio-unwritten
thread on that cpu is processing inode A's ioend work, it tries to
grab inode A's i_mutex lock.  Since the i_mutex lock of inode A is
still hold before the page fault happened, we enter a deadlock.

bitops: Move find_next_bit.o from lib-y to obj-y

If there are no builtin users of find_next_bit_le() and
find_next_zero_bit_le(), these functions are not present in the kernel
image, causing m68k allmodconfig to fail with:

This started to happen after commit 171d809df189 ("m68k: merge mmu and
non-mmu bitops.h"), as m68k had its own inline versions before.

commit 63e424c84429 ("arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,
BIT_LE, LAST_BIT}") added find_last_bit.o to obj-y (so it's always
included), but find_next_bit.o to lib-y (so it gets removed by the
linker if there are no builtin users).

On Sun4d systems running in SMP mode, IRQ 14 is used for timer interrupts
and has a specialized interrupt handler. IPI is currently set to use IRQ 14
as well, which causes it to trigger the timer interrupt handler, and not the
IPI interrupt handler.

normally handled interrupt. This IRQ is also used for SBUS interrupts,
however there is nothing in the IPI/SBUS interrupt handlers that indicate
that they will not handle sharing the interrupt.

This patch removes support for the SGX interrupt source in
the sh7372 INTCS controller.

The SGX hardware block included in sh7372 is already hooked
up to the ARM Cortex-A8 core using the INTCA controller,
so SGX users are encouraged to make use of that interrupt
source instead.

Removing support for the SGX interrupt source in INTCS
simplifies the sh7372 power management code by allowing
us to assume that only INTCA needs to be powered on to
operate the SGX hardware.

If the INTCS interrupt source would be kept then the kernel
would be forced to deal with additional dependencies that does
not follow the regular power domain hiearachy. With this

arch/powerpc/sysdev/fsl_rio.c: correct IECSR register clear value

This bug causes the IECSR register clear failure.  In this case, the RETE
(retry error threshold exceeded) interrupt will be generated and cannot be
cleared.  So the related ISR may be called persistently.

The RETE bit in IECSR is cleared by writing a 1 to it.

12 years agodrivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq.

drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to have irq.

The previous rtc-s3c had two issues related with its IRQ.

1. Users cannot open rtc multiple times because an open operation
   calls request_irq on the same IRQ.  (e.g., two user processes wants to
   open and read RTC time from rtc-s3c at the same time)

2. If alarm is set and no one has the rtc opened with filesystem
   (either the alarm is set by kernel/boot-loader or user set an alarm and
   closed rtc dev file), the pending bit is not cleared and no further
   interrupt is invoked.  When the alarm is used by the system itself such
   as a resume from suspend-to-RAM or other Low-power modes/idle, this is
   a critical issue.

This patch mitigates these issues by calling request_irq at probe and
free_irq at remove.

12 years agomemcg: fix hierarchical oom locking
Johannes Weiner [Thu, 25 Aug 2011 22:59:16 +0000 (15:59 -0700)]
memcg: fix hierarchical oom locking

Commit 79dfdaccd1d5 ("memcg: make oom_lock 0 and 1 based rather than
counter") tried to oom lock the hierarchy and roll back upon
encountering an already locked memcg.

The code is confused when it comes to detecting a locked memcg, though,
so it would fail and rollback after locking one memcg and encountering
an unlocked second one.

The result is that oom-locking hierarchies fails unconditionally and
that every oom killer invocation simply goes to sleep on the oom
waitqueue forever.  The tasks practically hang forever without anyone
intervening, possibly holding locks that trip up unrelated tasks, too.
