Revision 808e9df477757955a9644ca323010339be0c40ee authored by Gleb Fotengauer-Malinovskiy on 25 June 2021, 17:36:55 UTC, committed by Linus Torvalds on 25 June 2021, 17:53:26 UTC
This ioctl request reads from uffdio_continue structure written by
userspace which justifies _IOC_WRITE flag.  It also writes back to that
structure which justifies _IOC_READ flag.

See NOTEs in include/uapi/asm-generic/ioctl.h for more information.

Fixes: f619147104c8 ("userfaultfd: add UFFDIO_CONTINUE ioctl")
