This factors out a couple of\ncallsites and allows us to do further unifications.\n\nAlso, with this change specific_send_sig_info() does handle_stop_signal().\nNot that this is really important, we never send STOP/CONT via send_sig() and\nfriends, but still this looks more consistent.\n\nThe only (afaics) special case is get_signal_to_deliver(). If the traced task\ndequeues SIGCONT, it can re-send it to itself after ptrace_stop() if the\nsignal was blocked by debugger. In that case handle_stop_signal() is\nunnecessary, but hopefully not a problem.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c99fcf28b87d8cab592db7571e3164f5cb54c5b3", "tree": "356ce5d2b0bfd33794a81bf4cd90abd7859776da", "parents": [ "f8c5b5c06f63fe9aaebefbf9f0b79909066b1b6c" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Apr 30 00:52:49 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:35 2008 -0700" }, "message": "signals: send_group_sigqueue: don\u0027t take tasklist_lock\n\nhandle_stop_signal() was changed, now send_group_sigqueue() doesn\u0027t need\ntasklist_lock.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f8c5b5c06f63fe9aaebefbf9f0b79909066b1b6c", "tree": "58f7cde6d5b6c52ad927658521a32822661f048d", "parents": [ "5fc894bb4fb1de8373d1d5fb6db19204a16859e8" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Apr 30 00:52:49 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:35 2008 -0700" }, "message": "signals: __group_complete_signal: cache the value of p-\u003esignal\n\nCosmetic, cache p-\u003esignal to make the code a bit more readable.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5fc894bb4fb1de8373d1d5fb6db19204a16859e8", "tree": "167c513b50b8ceed48a8fb7e4c2e63397f0fa7d7", "parents": [ "5c193e8871b76f3bf8ed1e31f7af7c70890ebc4f" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Apr 30 00:52:48 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:35 2008 -0700" }, "message": "signals: send_sigqueue: don\u0027t forget about handle_stop_signal()\n\nsend_group_sigqueue() calls handle_stop_signal(), send_sigqueue() doesn\u0027t.\nThis is not consistent and in fact I\u0027d say this is (minor) bug.\n\nMove handle_stop_signal() from send_group_sigqueue() to do_send_sigqueue(),\nthe latter is called by send_sigqueue() too.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5c193e8871b76f3bf8ed1e31f7af7c70890ebc4f", "tree": "533b708c86908e8d1a439ef63a1c1515871715d7", "parents": [ "f6b76d4fb0039e077824be85ed4ac94e96beef86" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Apr 30 00:52:48 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:35 2008 -0700" }, "message": "signals: send_sigqueue: don\u0027t take rcu lock\n\nlock_task_sighand() was changed, send_sigqueue() doesn\u0027t need rcu_read_lock()\nany longer.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f6b76d4fb0039e077824be85ed4ac94e96beef86", "tree": "70a9ccff1d0194ff3a5ab23837f5a2ad839af6ba", "parents": [ "ad16a4606939ce1bedb79c87e412467be803e990" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Apr 30 00:52:47 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:35 2008 -0700" }, "message": "get_signal_to_deliver: use the cached -\u003esignal/sighand values\n\nCache the values of current-\u003esignal/sighand.
