2010-05-28ACPI: acpi_idle: touch TS_POLLING only in the non-MWAIT caseLen Brown1-12/+16
commit d306ebc28649b89877a22158fe0076f06cc46f60 (ACPI: Be in TS_POLLING state during mwait based C-state entry) fixed an important power & performance issue where ACPI c2 and c3 C-states were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH). That bug had been causing us to receive redundant scheduling interrups when we had already been woken up by MONITOR/MWAIT. Following up on that... In the MWAIT case, we don't have to subsequently check need_resched(), as that c heck was there for the TS_POLLING-clearing case. Note that not only does the cpuidle calling function already check need_resched() before calling us, the low-level entry into monitor/mwait calls it twice -- guaranteeing that a write to the trigger address can not go un-noticed. Also, in this case, we don't have to set TS_POLLING when we wake, because we never cleared it. Signed-off-by: Len Brown <[email protected]> Acked-by: Venkatesh Pallipadi <[email protected]>

The wrong size was being calculated for vfinfo.

Currently we disallow GSO packets on the IPv6 forward path. This patch fixes this. Note that I discovered that our existing GSO MTU checks (e.g., IPv4 forwarding) are buggy in that they skip the check altogether, when they really should be checking gso_size + header instead. I have also been lazy here in that I haven't bothered to segment the GSO packet by hand before generating an ICMP message. Someone should add that to be 100% correct.

BugLink: https://launchpad.net/bugs/586347 Symptom: On the Sony VPCS11V9E, using GStreamer-based applications with PulseAudio in Ubuntu 10.04 LTS results in stuttering audio. It appears to worsen with increased I/O. Test case: use Rhythmbox under increased I/O pressure. This symptom is reproducible in the current daily stable alsa-driver snapshots (at least up until 21 May 2010; later snapshots fail to build from source due to missing preprocessor directives when compiled against 2.6.32).

2010-05-27fs: introduce new truncate sequence[email protected]8-63/+300
Introduce a new truncate calling sequence into fs/mm subsystems. Rather than setattr > vmtruncate > truncate, have filesystems call their truncate sequence from ->setattr if filesystem specific operations are required. vmtruncate is deprecated, and truncate_pagecache and inode_newsize_ok helpers introduced previously should be used. simple_setattr is introduced for simple in-ram filesystems to implement the new truncate sequence. Eventually all filesystems should be converted to implement a setattr, and the default code in notify_change should go away. simple_setsize is also introduced to perform just the ATTR_SIZE portion of simple_setattr (ie. changing i_size and trimming pagecache). To implement the new truncate sequence: - filesystem specific manipulations (eg freeing blocks) must be done in the setattr method rather than ->truncate. - vmtruncate can not be used by core code to trim blocks past i_size in the event of write failure after allocation, so this must be performed in the fs code. - convert usage of helpers block_write_begin, nobh_write_begin, cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed variants. These avoid calling vmtruncate to trim blocks (see previous). - inode_setattr should not be used. generic_setattr is a new function to be used to copy simple attributes into the generic inode. - make use of the better opportunity to handle errors with the new sequence. Big problem with the previous calling sequence: the filesystem is not called until i_size has already changed. This means it is not allowed to fail the call, and also it does not know what the previous i_size was. Also, generic code calling vmtruncate to truncate allocated blocks in case of error had no good way to return a meaningful error (or, for example, atomically handle block deallocation).
