remove duplicate code in automount_update_mount()").

This was not duplicate code. The expire_tokens need to be handled as well:
Send 0 == success for MOUNT_DEAD (umount successful), do nothing for
MOUNT_UNMOUNTING (not yet done) and an error for everything else.

Otherwise the automount logic will assume unmounting is not done and will
not send any new requests for mounting. As a result, the corresponding
mount unit is never mounted.

Without this, automounts with TimeoutIdleSec= are broken. Once the idle
timeout triggered a umount, any access to the corresponding filesystem
hangs forever.

7 years agoutil-lib: Add sparc64 support for process creation (#3348)
Michael Karcher [Mon, 30 May 2016 00:03:51 +0000 (02:03 +0200)] 
util-lib: Add sparc64 support for process creation (#3348)

The current raw_clone function takes two arguments, the cloning flags and
a pointer to the stack for the cloned child. The raw cloning without
passing a "thread main" function does not make sense if a new stack is
specified, as it returns in both the parent and the child, which will fail
in the child as the stack is virgin. All uses of raw_clone indeed pass NULL
for the stack pointer which indicates that both processes should share the
stack address (so you better don't pass CLONE_VM).

This commit refactors the code to not require the caller to pass the stack
address, as NULL is the only sensible option. It also adds the magic code
needed to make raw_clone work on sparc64, which does not return 0 in %o0
for the child, but indicates the child process by setting %o1 to non-zero.
This refactoring is not plain aesthetic, because non-NULL stack addresses
need to get mangled before being passed to the clone syscall (you have to
apply STACK_BIAS), whereas NULL must not be mangled. Implementing the
conditional mangling of the stack address would needlessly complicate the
code.

raw_clone is moved to a separete header, because the burden of including
the assert machinery and sched.h shouldn't be applied to every user of
missing_syscalls.h
