[PATCH v4 1/2] dm suspend: return -ERESTARTSYS instead of -EINTR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit changes device mapper, so that it returns -ERESTARTSYS
instead of -EINTR when it is interrupted by a signal (so that the syscal
will restart the ioctl).

The manpage signal(7) says that the ioctl function should be restarted if
the signal was handled with SA_RESTART.
