  "message": "exec: simplify the new -\u003esighand allocation\n\nde_thread() pre-allocates newsighand to make sure that exec() can\u0027t fail after\nkilling all sub-threads. Imho, this buys nothing, but complicates the code:\n\n\t- this is (mostly) needed to handle CLONE_SIGHAND without CLONE_THREAD\n\t  tasks, this is very unlikely (if ever used) case\n\n\t- unless we already have some serious problems, GFP_KERNEL allocation\n\t  should not fail\n\n\t- ENOMEM still can happen after de_thread(), -\u003esighand is not the last\n\t  object we have to allocate\n\nChange the code to allocate the new -\u003esighand on demand.\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",
