https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v2.6.34.62008-07-26T19:00:10Ztask_current_syscall2008-07-26T19:00:10ZRoland McGrathroland@redhat.com2008-07-26T02:45:59Zurn:sha1:bbc698636ed48b6fcd323964e0f847a6a796325d
This adds the new function task_current_syscall() on machines where the
asm/syscall.h interface is supported (CONFIG_HAVE_ARCH_TRACEHOOK). It's
exported for modules to use in the future. This function safely samples
the state of a blocked thread to collect what system call it is blocked
in, and the six system call argument registers.
