If there are no listeners, taskstats_exit_send() just returns because taskstats_exit_alloc() didn't allocate *tidstats. This is wrong, each sub-thread should do fill_tgid_exit() on exit, otherwise its ->delays is not recorded in ->signal->stats and lost. Q: We don't send TASKSTATS_TYPE_AGGR_TGID when single-threaded process exits. Is it good? How can the listener figure out that it was actually a process exit, not sub-thread? Signed-off-by:

Fix a small memory leak in ubd_config, and clearify the confusion which lead to it. Then, some little changes not affecting operations - * move init functions together, * add a comment about a potential problem in case of some evolution in the block layer, * mark all initcalls as static __init functions * mark an used once little function as inline * document that mconsole methods are all called in process context (was triggered when checking ubd mconsole methods).

To simplify error handling, make sure fd is saved into ubd_dev->fd only when we are sure it is an fd and not an error code. Signed-off-by:

Pure whitespace and style fixes split out from subsequent patch. Some changes (err -> ret) don't make sense now, only later, but I split them out anyway since they cluttered the patch. Signed-off-by:

do_ubd is actually just a boolean variable - the way it is used currently is a leftover from the old 2.4 block layer, but it is still used; its use is suspicious, but removing it would be too intrusive for now and needs more thinking. Signed-off-by:

Add some comments about requirements for ubd_io_lock and expand its use. When an irq signals that the "controller" (i.e. another thread on the host, which does the actual requests and is the only one blocked on I/O on the host) has done some work, we call again the request function ourselves (do_ubd_request). We now do that with ubd_io_lock held - that's useful to protect against concurrent calls to elv_next_request and so on. XXX: Maybe we shouldn't call at all the request function. Input needed on this. Are we supposed to plug and unplug the queue? That code "indirectly" does that by setting a flag, called do_ubd, which makes the request function return (it's a residual of 2.4 block layer interface). Meanwhile, however, merge this patch, which improves things. Cc: Jens Axboe <axboe@suse.de> Signed-off-by:

This lock protects ubd setup and teardown, so is only used in process context; beyond that, during such setup memory allocations must be performed and some generic functions which can sleep must be called (such as add_disk()). So the only correct solution is to make it a mutex instead of a spin_lock. No other change is done - this lock must be acquired in different places but it's done afterwards. Signed-off-by:

To rethink locking, I needed to understand well what each function does. While doing this I renamed some: * ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev) * ubd_new_disk -> ubd_disk_register (it handles registration with the block layer - one hopes this makes clearer the difference with ubd_add()) Signed-off-by:

Rename the ubd_dev array to ubd_devs and then call any "struct ubd" ubd_dev instead of dev, which doesn't make clear what we're treating (and no, it's not hungarian notation - not any more than calling all vm_area_struct vma or all inodes inode). Signed-off-by:

With 256 minors and 16 minors used per each UBD device, we can allow the use of up to 16 UBD devices per UML. Also chnage parse_unit and leave to the caller (which already do it) the check for excess numbers, since this is just supposed to do raw parsing. Signed-off-by:

add_bd_holder() is called from bd_claim_by_kobject to put a given struct bd_holder in the list if there is no matching entry. There are 3 possible results of add_bd_holder(): 1. there is no matching entry and add the given one to the list 2. there is matching entry, so just increment reference count of the existing one 3. something failed during its course 1 and 2 are successful cases. But for case 2, someone has to free the unused struct bd_holder. The current code frees it inside of add_bd_holder and returns same value 0 for both cases 1 and 2. However, it's natural and less error-prone if caller frees it since it's allocated by the caller. Signed-off-by: -
