Subject: get_user() and put_user() missing in syscall list
Date: Mon, 2 Jun 2014 13:43:23 +0530 (IST) [thread overview]
Message-ID: <1994577982.6761.1401696804037.JavaMail.open-xchange@webmail.cdac.in> (raw)
In-Reply-To: <CAEK-7JLUqkSQNQP-utOTcSSiptddCV0yicv6mGUagk_nhe42dg@mail.gmail.com>
These two are not the system calls. they are the Kernel API's to transfer the
data from user address space to the kernel address space.
please see:
