exit: Rename complete_and_exit to kthread_complete_and_exit

2021-12-13T18:04:45+00:00

Update complete_and_exit to call kthread_exit instead of do_exit. Change the name to reflect this change in functionality. All of the users of complete_and_exit are causing the current kthread to exit so this change makes it clear what is happening. Move the implementation of kthread_complete_and_exit from kernel/exit.c to to kernel/kthread.c. As this function is kthread specific it makes most sense to live with the kthread functions. There are no functional change. Signed-off-by: "Eric W. Biederman"

signal: Remove the siginfo paramater from kernel_dqueue_signal

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29+00:00

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

signal: remove jffs2_garbage_collect_thread()->allow_signal(SIGCONT)

2015-11-07T01:50:42+00:00

jffs2_garbage_collect_thread() does allow_signal(SIGCONT) for no reason, SIGCONT will wake a stopped task up even if it is ignored.

signal: introduce kernel_signal_stop() to fix jffs2_garbage_collect_thread()

2015-11-07T01:50:42+00:00

jffs2_garbage_collect_thread() can race with SIGCONT and sleep in TASK_STOPPED state after it was already sent. Add the new helper, kernel_signal_stop(), which does this correctly.

signal: turn dequeue_signal_lock() into kernel_dequeue_signal()

2015-11-07T01:50:42+00:00

1. Rename dequeue_signal_lock() to kernel_dequeue_signal(). This matches another "for kthreads only" kernel_sigaction() helper. 2. Remove the "tsk" and "mask" arguments, they are always current and current->blocked. And it is simply wrong if tsk != current. 3. We could also remove the 3rd "siginfo_t *info" arg but it looks potentially useful. However we can simplify the callers if we change kernel_dequeue_signal() to accept info => NULL. 4. Remove _irqsave, it is never called from atomic context.

signals: jffs2: fix the wrong usage of disallow_signal()

2014-06-06T23:08:11+00:00

jffs2_garbage_collect_thread() does disallow_signal(SIGHUP) around jffs2_garbage_collect_pass() and the comment says "We don't want SIGHUP to interrupt us". But disallow_signal() can't ensure that jffs2_garbage_collect_pass() won't be interrupted by SIGHUP, the problem is that SIGHUP can be already pending when disallow_signal() is called, and in this case any interruptible sleep won't block. Note: this is in fact because disallow_signal() is buggy and should be fixed, see the next changes. But there is another reason why disallow_signal() is wrong: SIG_IGN set by disallow_signal() silently discards any SIGHUP which can be sent before the next allow_signal(SIGHUP). Change this code to use sigprocmask(SIG_UNBLOCK/SIG_BLOCK, SIGHUP). This even matches the old (and wrong) semantics allow/disallow had when this logic was written.

jffs2: Convert most D1/D2 macros to jffs2_dbg

2012-03-26T23:39:24+00:00

D1 and D2 macros are mostly uses to emit debugging messages. Convert the logging uses of D1 & D2 to jffs2_dbg(level, fmt, ...) to be a bit more consistent style with the rest of the kernel. All jffs2_dbg output is now at KERN_DEBUG where some of the previous uses were emitted at various KERN_s. Signed-off-by: Joe Perches Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse
