2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-12[PATCH] tty: update the tty layer to work with struct pidEric W. Biederman
Of kernel subsystems that work with pids the tty layer is probably the largest consumer. But it has the nice virtue that the assiation with a session only lasts until the session leader exits. Which means that no reference counting is required. So using struct pid winds up being a simple optimization to avoid hash table lookups. In the long term the use of pid_nr also ensures that when we have multiple pid spaces mixed everything will work correctly. Signed-off-by: Eric W.

2007-02-11[PATCH] uml: x86_64 ptrace fixesJeff Dike
This patch fixes some missing ptrace bits on x86_64. PTRACE_ARCH_PRCTL is hooked up and implemented. This required generalizing arch_prctl_skas slightly to take a task_struct to modify. Previously, it always operated on current. Reading and writing the debug registers is also enabled by un-ifdefing the code that implements that. It turns out that x86_64 is identical to i386, so the same code can be used.

2007-02-11[PATCH] uml: x86_64 thread fixesJeff Dike
x86_64 needs some TLS fixes. What was missing was remembering the child thread id during clone and stuffing it into the child during each context switch. The %fs value is stored separately in the thread structure since the host controls what effect it has on the actual register file. The host also needs to store it in its own thread struct, so we need the value kept outside the register file. arch_prctl_skas was fixed to call PTRACE_ARCH_PRCTL appropriately. There is some saving and restoring of registers in the ARCH_SET_* cases so that the correct set of registers are changed on the host and restored to the process when it runs again.

2007-02-11[PATCH] uml: fix error output during early bootJeff Dike
The startup code panics a lot if anything goes wrong early on. This is wrong for several reasons, like the kernel isn't running, so you can't really be calling into it yet, but the harm comes from useful error messages being trapped in the printk ring where no one will ever see them. This patch changes these panics to perror and printf in wrappers which also exit. Normal, informational, prints are also wrapped so that fflush(stdout) is called after each one. This is so the output appears in the correct sequence in the event of an error.

Complications - There was no way to get a request struct (and queue) from the structure sent to the io_thread, so a pointer to the request was added. This is needed in ubd_handler in order to kick do_ubd_request to process another request. Queue initialization is moved from ubd_init to ubd_add.
