  "message": "tracehook: TIF_NOTIFY_RESUME\n\nThis adds tracehook.h inlines to enable a new arch feature in support of\nuser debugging/tracing.  This is not used yet, but it lays the groundwork\nfor a debugger to be able to wrangle a task that\u0027s possibly running,\nwithout interrupting its syscalls in progress.\n\nEach arch should define TIF_NOTIFY_RESUME, and in their entry.S code treat\nit much like TIF_SIGPENDING.  That is, it causes you to take the slow path\nwhen returning to user mode, where you get the full user-mode state\naccessible as for signal handling or ptrace.  The arch code should check\nTIF_NOTIFY_RESUME after handling TIF_SIGPENDING.  When it\u0027s set, clear it\nand then call tracehook_notify_resume().\n\nIn future, tracing code will call set_notify_resume() when it wants to get\na callback in tracehook_notify_resume().\n\nSigned-off-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
