Failed GFP_ATOMIC allocations by the network stack result in dropped

These warnings are harmless, but they still cause users to panic and

When failure occurs at the last looping cycle (when 'i == 0'), it will
print "bad PC value" instead of "(%08x) ", which needs additional 1
byte.
If not add 1 byte, the str will not be NUL terminated, and the next
printk() will cause issue.

Final cleanup: Some minor points that I noticed while writing the
previous 3 patches
1) The name try_atomic_semop() is misleading: The function performs the
operation (if it is possible).
2) Some documentation updates.
No real code change, a rename and documentation changes.
Signed-off-by:
Introduce seperate queues for operations that do not modify the
semaphore values.
Advantages:
- Simpler logic in check_restart().
- Faster update_queue(): Right now, all wait-for-zero operations
are always tested, even if the semaphore value is not 0.
- wait-for-zero gets again priority, as in
There are two places that can contain alter operations:
- the global queue: sma->pending_alter
- the per-semaphore queues: sma->sem_base[].pending_alter.
Since one of the queues must be processed first, this causes an odd
priorization of the wakeups:
Right now, complex operations have priority
do_smart_update_queue() is called when an operation
(semop, semctl(SETVAL), semctl(SETALL), ...) modified the array.
It must check which of the sleeping tasks can proceed.
do_smart_update_queue() missed a few wakeups:
- if a sleeping complex op was completed, then all per-semaphore queues
must
I've split my patch into 4 parts:
- 1: Fix-missing-wakeups-in-do_smart_update

How do you know the disk is completely idle ? How much cache memory do
your controller and disk have ? Why do you think the requests should trigger
action of disk immediately while you don't know what kind of requests are they.
They are reading the same offset of the same block ?

For NULL terminated string, need always be sure of ended by zero.
'command_line' is a static variable which will be initialized

int otime, struct list_head
Dear list,
In order to debug I/O performance, I recently wrote a tiny program for
inspecting /sys/block/$DISK/stat. It works by dumping deltas of the values
every 100 ms, quite simply (except the queue-length value, for which
deltas are clearly useless).
Using this, I often see periods
/dev/oldmem provides the interface for us to access the old memory in
the dump-capture kernel. Unfortunately, no one actually uses this interface.
And this interface could actually cause some real problems if used on ia64
where the cached/uncached accesses are mixed. See the discussion from
the

hi,
Here anyone use linux kernel 2.6.38, this version still supported?
No, please move to a more recent kernel, that is quite old and obsolete.

have removed that interface, so saved_max_pfn is now unneeded in ia64,
and we needn't set it anymore.

For NULL terminated string, need always be sure of ended by zero.
'command_line' is a static variable which will be initialized
automatically, and cmdline_init() is __init function, so need not
initialize it again, can just use strlcpy instead of strncpy.

For NUL terminated string, need always be sure of ended by zero.
Or the next pr_info() will cause issue.

According to the areas which use %16.16s within this file, the
'sdev-modalias' may not always be a NUL terminated string.
So need use %.16s instead of %s in pr_err(), or may cause issue.

(tracing: Add a proc file to stop tracing and free buffer)
implement a method to free up ring buffer in kernel memory
in the release code path of free_buffer's fd.
Then we don't need read/write support for free_buffer,
indeed we just have a dummy

Fred，
How do you know the disk is completely idle ? How much cache memory do
your controller and disk have ? Why do you think the requests should trigger
action of disk immediately while you don't know what kind of requests are they.
They are reading the same offset of the same block ?

Why? any reference? This reasoning is really weak.
