[PATCH v2 0/5] [RFC] copy_strtok_from_user

[Steven Rostedt <rostedt@goodmis.org>]

This is the second series of the uaccess code.

Changes in v2:

 - moved probe_kernel_* functions to lib/uaccess.c

 - renamed copy_word_from_user to copy_strtok_from_user.

 - changed copy_strtok_from_user to pass in a delimiter string.
   ftrace defines SPACE to be ' \t\r\n'.

Ingo,
I added your copy right to lib/uaccess.c since git blame shows you
as the author of the probe_kernel_* code. Also, is it OK that I
added the "GPL v2" line in that file as well?

Andrew,
Since you are, in essence, the memory maintainer, could you give
your Acked-by: to the copy_strtok_from_user code.

The probe_kernel code is still EXPORT_SYMBOL_GPL, and I added
that too to copy_strtok_from_user. Are there any objections to that?
