TRACEHOOK_NOTIFY_RES(9) | Kernel Internals | TRACEHOOK_NOTIFY_RES(9) |
NAME¶
tracehook_notify_resume - report when about to return to user mode
SYNOPSIS¶
void tracehook_notify_resume(struct pt_regs * regs);
ARGUMENTS¶
regs
user-mode registers of current task
DESCRIPTION¶
This is called when TIF_NOTIFY_RESUME has been set. Now we are about to return to user mode, and the user state in regs can be inspected or adjusted. The caller in arch code has cleared TIF_NOTIFY_RESUME before the call. If the flag gets set again asynchronously, this will be called again before we return to user mode.
Called without locks. However, on some machines this may be called with interrupts disabled.
