Now that\nwe demote the leader to a thread there is no longer any reason to change\nit\u0027s parentage.\n\nNot changing our ptrace parents is a user visible change if someone\nlooks hard enough. I don\u0027t think user space applications will care or\neven notice.\n\nIn the practical and I think common case a debugger will have attached\nto all of the threads using the same ptrace flags. From my quick skim\nof strace and gdb that appears to be the case. Which if true means\ndebuggers will not notice a change.\n\nBefore this point we have already generated a ptrace event in do_exit\nthat reports the leaders pid has died so de_thread is visible to a\ndebugger. Which means attempting to hide this case by copying flags\naround appears excessive.\n\nBy not doing anything it avoids all of the weird locking issues between\nde_thread and ptrace attach, and removes one case from consideration for\nfixing the ptrace locking.\n\nThis only addresses Oleg\u0027s first concern with ptrace_attach, that of the\nproblems caused by reparenting. Oleg\u0027s second concern is essentially a\nrace between ptrace_attach and release_task that causes an oops when we\nget to force_sig_specific.

The simplest is a long standing double decrement of\n__get_cpu_var(process_counts) in __unhash_process. Caused by\ntwo processes exiting when only one was created.\n\nThe other is that since we no longer detach from the thread_group list\nit is possible for do_each_thread when run under the tasklist_lock to\nsee the same task_struct twice. Once on the task list as a\nthread_group_leader, and once on the thread list of another\nthread.\n\nThe double appearance in do_each_thread can cause a double increment\nof mm_core_waiters in zap_threads resulting in problems later on in\ncoredump_wait.\n\nTo remedy those two problems this patch takes the simple approach\nof changing the old thread group leader into a child thread.\nThe only routine in release_task that cares is __unhash_process,\nand it can be trivially seen that we handle cleaning up a\nthread group leader properly.\n\nSince de_thread doesn\u0027t change the pid of the exiting leader process\nand instead shares it with the new leader process. I change\nthread_group_leader to recognize group leadership based on the\ngroup_leader field and not based on pids. This should also be\nslightly cheaper then the existing thread_group_leader macro.\n\nI performed a quick audit and I couldn\u0027t see any user of\nthread_group_leader that cared about the difference.\n\nSigned-off-by: Eric W.

Truncate\nwon\u0027t block on the writeout because the page isn\u0027t in pagecache any more.\nSo truncate will the free the blocks from the file under the page\u0027s feet.\nThen something else can reallocate those blocks.
