We shouldn't be using the os wrappers from os code - we can use libc directly. This patch replaces wrapper calls with libc calls. It turns out that os_sigio_async had only one caller, which was in startup.c, so that function is moved there and its name changed. Signed-off-by:

Some small locking and formatting fixes in the ubd driver. Signed-off-by:

Jeff Dike authored
Replace global queue and lock with per-device queues and locks. Mostly a straightforward replacement of ubd_io_lock with dev->lock and ubd_queue with dev->queue. 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. Signed-off-by:

Eliminate the open_mutex after complaints from Blaisorblade. It turns out that the tty count provides the information needed to tell whether we are the first opener or last closer. Signed-off-by:

Remove the last vestiges of devfs from console registration. Change the name of the function, plus remove a couple of unused fields from the line_driver structure. struct lines is no longer needed, all traces of it are gone. The only way that I can see to mark a structure as being almost-const is to individually const the fields. This is the case for the line_driver structure, which has only one modifiable field - a list_head in a sub-structure. Signed-off-by:

Jeff Dike authored
The chan_opts structure is mostly const, and needs no locking. Comment the lack of locking on the one field that can change. Make all the other fields const. It turned out that console_open_chan didn't use its chan_opts argument, so that is deleted from the function and its callers. Signed-off-by:

Locking fixes. Locking was totally lacking for the mconsole_devices, which got a spin lock, and the unplugged pages data, which got a mutex. The locking of the mconsole console output code was confused. Now, the console_lock (renamed to client_lock) protects the clients list. Signed-off-by:

The registration of host network transports needed some locking. The transport list itself is locked, but calls to the registration routines are not. This is compensated for by checking that a transport structure is not yet on any list. I also took the opportunity to const all fields in the transport structure except the list, which obviously can be modified. Signed-off-by:

Some comment and whitespace cleanups in the console and mconsole code. Signed-off-by:
-
Jeff Dike authored
I noticed that errors happening while hotplugging devices from the host were never returned back to the mconsole client. In some cases, success was returned instead of even an information-free error. This patch cleans that up by having the low-level configuration code pass back an error string along with an error code. At the top level, which knows whether it is early boot time or responding to an mconsole request, the string is printk'd or returned to the mconsole client. There are also whitespace and trivial code cleanups in the surrounding code. Signed-off-by:
