2010-10-27fasync: Fix placement of FASYNC flag commentLinus Torvalds1-3/+3
In commit f7347ce4ee7c ("fasync: re-organize fasync entry insertion to allow it under a spinlock") Arnd took an earlier patch of mine that had the comment about the FASYNC flag above the wrong function. When the fasync_add_entry() function was split to introduce the new fasync_insert_entry() helper function, the code that actually cares about the FASYNC bit moved to that new helper. So just move the comment to the right point. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The taskstats interface uses microsecond granularity for the user and system time values. The conversion from cputime to the taskstats values uses the cputime_to_msecs primitive which effectively limits the granularity to milliseconds. Add the cputime_to_usecs primitive for architectures that have better, more precise CPU time values. Remove cputime_to_msecs primitive because there are no more users left.

2010-10-27delayacct: align to 8 byte boundary on 64-bit systemsJeff Mahoney1-1/+7
prepare_reply() sets up an skb for the response. The payload contains: +--------------------------------+ | genlmsghdr - 4 bytes | +--------------------------------+ | NLA header - 4 bytes | /* Aggregate header */ +-+------------------------------+ | | NLA header - 4 bytes | /* PID header */ | +------------------------------+ | | pid/tgid - 4 bytes | | +------------------------------+ | | NLA header - 4 bytes | /* stats header */ | + -----------------------------+ <- oops. aligned on 4 byte boundary | | struct taskstats - 328 bytes | +-+------------------------------+ The start of the taskstats struct must be 8 byte aligned on IA64 (and other systems with 8 byte alignment rules for 64-bit types) or runtime alignment warnings will be issued. This patch pads the pid/tgid field out to sizeof(long), which forces the alignment of taskstats. The getdelays userspace code is ok with this since it assumes 32-bit pid/tgid and then honors that header's length field. An array is used to avoid exposing kernel memory contents to userspace in the response.

2010-10-27delay-accounting: reimplement -c for getdelays.c to report information on a ↵Mel Gorman1-2/+36
target command Task delay-accounting was identified as one means of determining how long a process spends in congestion_wait() without adding new statistics. For example, if the workload should not be doing IO, delay-accounting could reveal how long it was spending in unexpected IO or delays. Unfortunately, on closer examination it was clear that getdelays does not act as documented. Commit a3baf649 ("per-task-delay-accounting: documentation") added Documentation/accounting/getdelays.c with a -c switch that was documented to fork/exec a child and report statistics on it but for reasons that are unclear to me, commit 9e06d3f9 deleted support for this switch but did not update the documentation. It might be an oversight or it might be because the control flow of the program meant that accounting information would be printed once early in the lifetime of the program making it of limited use. This patch reimplements -c for getdelays.c to act as documented. Unlike the original version, it waits until the command completes before printing any information on it. An example of it being used looks like $ ./getdelays -d -c find /home/mel -name mel print delayacct stats ON /home/mel /home/mel/.notes-wine/drive_c/windows/profiles/mel /home/mel/.wine/drive_c/windows/profiles/mel /home/mel/git-configs/dot.kde/share/apps/konqueror/home/mel PID 5923 CPU count real total virtual total delay total 42779 5051232096 5164722692 564207988 IO count delay total 41727 97804147758 SWAP count delay total 0 0 RECLAIM count delay total 0 0 [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Mel Gorman <mel@csn.ul.ie> Acked-by: Balbir Singh <balbir@in.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1.

Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

2010-10-27rapidio: add relation links between RIO device structuresAlexandre Bounine2-33/+27
Create back and forward links between RIO devices. These links are intended for use by error management and hot-plug extensions. Links for redundant RIO connections between switches are not set (will be fixed in a separate patch).

2010-10-27rapidio: fix RapidIO sysfs hierarchyAlexandre Bounine3-1/+3
This set of RapidIO patches extends support for standard error recovery mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and CPS-1616. Implementation of the standard error-stopped state recovery mechanism (as defined by the RapidIO specification) is required for the new switches. Version 2 of this set of patches addresses received comments and fixes an error notification setup issue found in the idt_gen2.c after the first version was released. This patch: Make RapidIO devices appear in /sys/devices/rapidio directory instead of top of /sys/devices directory.
