2008-03-04resubmit: cciss: procfs updates to display info about manyMike Miller
volumes This patch allows us to display information about all of the logical volumes configured on a particular controller without stepping on memory even when there are many volumes (128 or more) configured.

2008-03-04splice: only return -EAGAIN if there's hope of more dataJens Axboe
sys_tee() currently is a bit eager in returning -EAGAIN, it may do so even if we don't have a chance of anymore data becoming available. So improve the logic and only return -EAGAIN if we have an attached writer to the input pipe. Reported by Johann Felix Soden <johfel@gmx.de> and Patrick McManus <mcmanus@ducksong.com>.

2008-03-03[PATCH] fs/ocfs2/aops.c: Correct use of ! and &Julia Lawall
In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider.

Commit f1f540688eae66c274ff1c1133b5d9c687b28f58 "optimized" ocfs2_data_convert_worker() to "only do work for regular files". Unfortunately, I left out a '!', which casued it to *skip* regular files.

2008-03-03exit_notify: fix kill_orphaned_pgrp() usage with mt exitOleg Nesterov
1. exit_notify() always calls kill_orphaned_pgrp(). This is wrong, we should do this only when the whole process exits. 2. exit_notify() uses "current" as "ignored_task", obviously wrong. Use ->group_leader instead. Test case: void hup(int sig) { printf("HUP received\n"); } void *tfunc(void *arg) { sleep(2); printf("sub-thread exited\n"); return NULL; } int main(int argc, char *argv[]) { if (!fork()) { signal(SIGHUP, hup); kill(getpid(), SIGSTOP); exit(0); } pthread_t thr; pthread_create(&thr, NULL, tfunc, NULL); sleep(1); printf("main thread exited\n"); syscall(__NR_exit, 0); return 0; } output: main thread exited HUP received Hangup With this patch the output is: main thread exited sub-thread exited HUP received Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-03-03will_become_orphaned_pgrp: partially fix insufficient ->exit_state checkOleg Nesterov
p->exit_state != 0 doesn't mean this process is dead, it may have sub-threads. Change the code to use "p->exit_state && thread_group_empty(p)" instead. Without this patch, ^Z doesn't deliver SIGTSTP to the foreground process if the main thread has exited. However, the new check is not perfect either. There is a window when exit_notify() drops tasklist and before release_task(). Suppose that the last (non-leader) thread exits. This means that entire group exits, but thread_group_empty() is not true yet. As Eric pointed out, is_global_init() is wrong as well, but I did not dare to do other changes. Just for the record, has_stopped_jobs() is absolutely wrong too. But we can't fix it now, we should first fix SIGNAL_STOP_STOPPED issues. Even with this patch ^Z doesn't play well with the dead main thread. The task is stopped correctly but do_wait(WSTOPPED) won't see it. This is another unrelated issue, will be (hopefully) fixed separately. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
