The BKL was pushed into this function when it was converted to use the unlocked_ioctl interface, but nothing that the function touches is actually protected by the BKL. So just remove the BKL entirely, so that we finally can get a realistic system build without the BKL being enabled at all. Signed-off-by:Linus Torvalds <torvalds@linux-foundation.org>

In commit f7347ce4 ("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:

Add a new __kfifo_int_must_check_helper() helper function, which is needed for kfifo_alloc() to return the right signed integer value. The origin __kfifo_must_check_helper() helper was renamed into __kfifo_uint_must_check_helper() to show the sign which is expected and returned.

dma64_addr_t looks pointless (at least there is no point that an architecture has the own dma64_addr_t typedef). dma_addr_t is set to 32 or 64 bits appropriately. You can use u64 at places where you know that 64 bit address is always necessary. Let's use u64 instead for mips. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system. Signed-off-by:
