util-linux/mount/mount.c calls the mount function in glibc, but that's just a trivial wrapper for the kernel system call. In fact it's so trivial that the glibc source code doesn't have an explicit implementation for it, but just automatically generates a syscall stub. The actual mount syscall implementation is in fs/namespace.c in the kernel source, and I suspect it's this you're interested in rather than the fiddly details of how a userspace function call turns into a syscall. Start at the sys_mount function. Cheers, -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
