+Subject: [PATCH] ioctl.c: Fix build with linux 4.17
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since kernel 4.17-rc1, sys_* syscalls can no longer be called directly:
+819671ff849b ("syscalls: define and explain goal to not call syscalls in the kernel")
+
+Since cryptodev uses sys_close() - and this has been removed in commit:
+2ca2a09d6215 ("fs: add ksys_close() wrapper; remove in-kernel calls to sys_close()")
+cryptodev has to be updated to use the ksys_close() wrapper.
