fcntl: rename F_OWNER_GID to F_OWNER_PGRP

2009-11-18T01:40:33Z

This is for consistency with various ioctl() operations that include the suffix "PGRP" in their names, and also for consistency with PRIO_PGRP, used with setpriority() and getpriority(). Also, using PGRP instead of GID avoids confusion with the common abbreviation of "group ID". I'm fine with anything that makes it more consistent, and if PGRP is what is the predominant abbreviation then I see no need to further confuse matters by adding a third one.

IRQ: Change __softirq_pending to unsigned int in asm-generic/hardirq.h.

2009-10-09T20:38:21Z

Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d ("asm-generic: add generic versions of common headers") the generic version of defined __softirq_pending as unsigned long. Which is different from other architectures for no apparent good reason and was causing the following warning: kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick': kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int' Reported and initial patch by Wu Zhangjin . Signed-off-by: Ralf Baechle Acked-by: Arnd Bergmann [ Arnd points out that we really should make sure parisc and alpha are ok with this, since they have also been converted to use the generic hardirq.h file. But neither seems to use it, although parisc does build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also appears unused.. - Linus ] Signed-off-by: Linus Torvalds

asm-generic/gpio.h: pull in linux/kernel.h for might_sleep()

2009-10-01T23:11:11Z

The asm-generic/gpio.h header uses the might_sleep() macro but doesn't include the header for it, so any source code that might include linux/gpio.h before linux/kernel.h can easily lead to a build failure. Signed-off-by: Mike Frysinger Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Optimize the ordering of sections in RW_DATA_SECTION.

2009-09-25T00:16:21Z

The old RW_DATA_SECTION had INIT_TASK_DATA (which was more-than-PAGE_SIZE-aligned), followed by a bunch of small alignment stuff, followed by more PAGE_SIZE-aligned stuff, so you wasted memory in the middle of .data re-aligning back up to PAGE_SIZE. This patch sorts the sections by alignment requirements, which should pack them essentially optimally. Signed-off-by: Tim Abbott Reviewed-by: Sam Ravnborg Signed-off-by: Linus Torvalds

fcntl: add F_[SG]ETOWN_EX

2009-09-24T14:21:01Z

In order to direct the SIGIO signal to a particular thread of a multi-threaded application we cannot, like suggested by the manpage, put a TID into the regular fcntl(F_SETOWN) call. It will still be send to the whole process of which that thread is part. Since people do want to properly direct SIGIO we introduce F_SETOWN_EX. The need to direct SIGIO comes from self-monitoring profiling such as with perf-counters. Perf-counters uses SIGIO to notify that new sample data is available. If the signal is delivered to the same task that generated the new sample it can augment that data by inspecting the task's user-space state right after it returns from the kernel. This is esp. convenient for interpreted or virtual machine driven environments. Both F_SETOWN_EX and F_GETOWN_EX take a pointer to a struct f_owner_ex as argument: struct f_owner_ex { int type; pid_t pid; }; Where type is one of F_OWNER_TID, F_OWNER_PID or F_OWNER_GID.
