[PATCH] syscalls: Fix file path names in the header comments

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Some of the syscall definitions have moved due to the original source
file being moved into a sub-directory. Update the file path names to
reflect that.

A couple of syscalls such as lookup_dcookie() and nfsservctl() don't
have a syscall definition anymore. Clear the filename and leave the
original subsystem name intact for reference.

Arguably, having filenames in comments might not be the best idea. If the
intention is to make it easier to find a syscall definition, it is probably
faster to just use 'git grep SYSCALL_DEFINE | grep <syscall_name>'. Please let
me know if it would be preferable to just get rid of these comments all
together.
