      [PATCH] delay accounting taskstats interface send tgid once · ad4ecbcb
      由 Shailabh Nagar 提交于 
      Send per-tgid data only once during exit of a thread group instead of once
with each member thread exit.

Currently, when a thread exits, besides its per-tid data, the per-tgid data
of its thread group is also sent out, if its thread group is non-empty.
The per-tgid data sent consists of the sum of per-tid stats for all
*remaining* threads of the thread group.

This patch modifies this sending in two ways:

- the per-tgid data is sent only when the last thread of a thread group
  exits.  This cuts down heavily on the overhead of sending/receiving
  per-tgid data, especially when other exploiters of the taskstats
  interface aren't interested in per-tgid stats

- the semantics of the per-tgid data sent are changed.  Instead of being
  the sum of per-tid data for remaining threads, the value now sent is the
  true total accumalated statistics for all threads that are/were part of
  the thread group.

The patch also addresses a minor issue where failure of one accounting
subsystem to fill in the taskstats structure was causing the send of
taskstats to not be sent at all.

The patch has been tested for stability and run cerberus for over 4 hours
on an SMP.

      [SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver · ede1e6f8
      由 HighPoint Linux Team 提交于 
      HighPoint RocketRAID 3220/3320 series 8 channel PCI-X SATA RAID Host
Adapters.

Fixes from original submission:

Merge Andrew Morton's patches:
- Provide locking for global list
- Fix debug printks
- uninline function with multiple callsites
- coding style fixups
- remove unneeded casts of void*
- kfree(NULL) is legal
- Don't "succeed" if register_chrdev() failed - otherwise we'll later
  unregister a not-registered chrdev.
- Don't return from hptiop_do_ioctl() with the spinlock held.
- uninline __hpt_do_ioctl()

Update for Arjan van de Ven's comments:
- put all asm/ includes after the linux/ ones
- replace mdelay with msleep
- add pci posting flush
- do not set pci command reqister in map_pci_bar
- do not try merging sg elements in hptiop_buildsgl()
- remove unused outstandingcommands member from hba structure
- remove unimplemented hptiop_abort() handler
- remove typedef u32 hpt_id_t

Other updates:
- fix endianess
