[PATCH 0/1] MR5375: server: Avoid removing thread twice from its desktop thread list.

[Rémi Bernon (＠rbernon)]

When a process is made a system process, `release_thread_desktop( thread, 0 )` is called and we remove the process threads from their desktop thread list, as well as decrementing the desktop user count. Later, when the process gets killed on shutdown, `release_thread_desktop( thread, 1 )` is called, and we remove the thread list node again.

This is 1) wrong, we only want to decrement the desktop user count in this case, and 2) causes an invalid write and corrupts the list the second time we remove the entry.
