dm suspend: return -ERESTARTSYS instead of -EINTR
This commit changes device mapper, so that it returns -ERESTARTSYS instead of -EINTR when it is interrupted by a signal (so that the ioctl can be restarted). The manpage signal(7) says that the ioctl function should be restarted if the signal was handled with SA_RESTART. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Cc: stable@vger.kernel.org
