[Valgrind-users] README_MISSING_SYSCALL_OR_IOCTL out of date with V 1.9.6

[Anne D. <an...@ma...>]

Very very small point but could be important for someone new to
Valgrind -- I had to do some hunting to figure out how to change my
personalized IOCTLs from 1.0.x. (I use Valgrind on click, which is
custom packet handling software with a Linux kernel-loadable module
that defines several of its own IOCTLs.)

"README_MISSING_SYSCALL_OR_IOCTL" still talks about calling
"must_be_readable" and "must_be_writable". It looks like these should
be changed to SYSCALL_TRACK(pre_mem_read, ...) and
SYSCALL_TRACK(pre_mem_write, ...).

One question: What's the difference between 'pre_mem_read' and
'pre_mem_read_asciiz'?
