Hi, NFS/VFS gurus
nfs_access_cache_shrinker() calls igrab() without serialized with

I think we need to serialize the generic_shutdown_super() and

Why not indeed. Maybe I should try to use my brain sometime.

Thanks Kumar/Morton/Kim
I shall make a small paragraph which describes the TDM driver
architecture and the interfaces it exposes.
As far as 8315 TDM is concerned it is a non QE driver and quite
different from this except for the functionality and external interface
it exposes.
Right now TDM is n

Hi,
Looking through hrtimer.c I noticed
static void __devinit init_hrtimers_cpu(int cpu)
static int __cpuinit hrtimer_cpu_notify(struct notifier_block *self,
unsigned long action, void *hcpu)
Couldn't the first be __cpuinit as well?

Ok, I checked all users of the create*workqueue() API now.
Turns out that there are many users that give a dynamic string as the
workqueue name (only the first three are relevant for the problem at
hand because the others are single-threaded):
drivers/connector/cn_queue.c
drivers/media/video/ivt

Make the if-else straight in __sync_single_inode().
No behavior change.

The `truncated' page in block_write_full_page() may stick for a long time.
E.g. ext2_rmdir() will set i_size to 0, and then the dir inode may hang around
because of being referenced by someone.
So clear PAGECACHE_TAG_DIRTY to prevent pdflush from retrying and iowaiting on
it.

Convert to requeue_io_wait() for case:
pages skipped due to locked buffers.

Introduce writeback_control.more_io to indicate that more I/O is
scheduled for this wakeup of pdflush.
Note that more_io is only updated on the _visited_ superblocks,
which prevents pdflush deamons from interfering with one another.

Merge duplicate code from background_writeout() and wb_kupdate() into
writeback_some_pages().
The pages_skipped in background_writeout() is ignored. The inode cannot be
written now will be retried in the next run of pdflush, typically in 5s.
