2006-10-31[PATCH] md: check bio address after mapping through partitions.NeilBrown
Partitions are not limited to live within a device. So we should range check after partition mapping. Note that 'maxsector' was being used for two different things. I have split off the second usage into 'old_sector' so that maxsector can be still be used for it's primary usage later in the function.

2006-10-31[PATCH] taskstats: fix sub-threads accountingOleg Nesterov
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?

2006-10-31[PATCH] uml ubd driver: ubd_io_lock usage fixupPaolo 'Blaisorblade' Giarrusso
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.

2006-10-31[PATCH] uml ubd driver: change ubd_lock to be a mutexPaolo 'Blaisorblade' Giarrusso
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.

2006-10-31[PATCH] uml ubd driver: give better names to some functions.Paolo 'Blaisorblade' Giarrusso
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: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Cc: Jeff Dike <jdike@addtoit.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-10-30[SPARC64]: Fix Tomatillo/Schizo IRQ handling.David S. Miller
The code in schizo_irq_trans_init() should set irq_data->sync_reg to the location of the SYNC register if this is Tomatillo, and set it to zero otherwise. But that is not what it is doing. As a result, non-Tomatillo systems were trying to access a non-existent register resulting in bus errors at the first PCI interrupt. Thanks to Roland Stigge for the bug report.

2006-10-30[PATCH] clean up add_bd_holder()Jun'ichi Nomura
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.

2006-10-30[PATCH] sunrpc: fix refcounting problems in rpc serversNeil Brown
A recent patch fixed a problem which would occur when the refcount on an auth_domain reached zero. This problem has not been reported in practice despite existing in two major kernel releases because the refcount can never reach zero. This patch fixes the problems that stop the refcount reaching zero. 1/ We were adding to the refcount when inserting in the hash table, but only removing from the hashtable when the refcount reached zero. Obviously it never would. So don't count the implied reference of being in the hash table. 2/ There are two paths on which a socket can be destroyed. One called svcauth_unix_info_release(). The other didn't. So when the other was taken, we can lose a reference to an ip_map which in-turn holds a reference to an auth_domain So unify the exit paths into svc_sock_put. This highlights the fact that svc_delete_socket has slightly odd semantics - it does not drop a reference but probably should. Fixing this need a bit more thought and testing.
