... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.

Allow the WM8994 to completely power off, including disabling the LDOs if they are software controlled, when it goes idle. The CODEC subdevice controls activity for the MFD as a whole. If the GPIOs need to be used while the device is active runtime PM should be disabled for the device by machine specific code.

Allow MFD cells to have pm_runtime_no_callbacks() called on them during registration. This causes the runtime PM framework to ignore them, allowing use of runtime PM to suspend the device as a whole even if not all drivers for the MFD can usefully implement runtime PM. For example, RTCs are likely to run continuously regardless of the power state of the system.

When open(2) without O_DIRECTORY opens an existing dir, it should return EISDIR. In do_last(), the variable 'error' is initialized EISDIR, but it is changed by d_revalidate() which returns any positive to represent 'the target dir is valid.' Should we keep and return the initialized 'error' in this case. Signed-off-by: NNick Piggin <npiggin@kernel.dk>

Po-Yu Chuang <ratbert.chuang@gmail.com> noticed that hlist_bl_set_first could crash on a UP system when LIST_BL_LOCKMASK is 0, because LIST_BL_BUG_ON(!((unsigned long)h->first & LIST_BL_LOCKMASK)); always evaulates to true. Fix the expression, and also avoid a dependency between bit spinlock implementation and list bl code (list code shouldn't know anything except that bit 0 is set when adding and removing elements). Eventually if a good use case comes up, we might use this list to store 1 or more arbitrary bits of data, so it really shouldn't be tied to locking either, but for now they are helpful for debugging.

As J. R. Okajima noted, force_reval_path passes in the same dentry to d_revalidate as the one in the nameidata structure (other callers pass in a child), so the locking breaks. This can oops with a chrooted nfs mount, for example. Similarly there can be other problems with revalidating a dentry which is already in nameidata of the path walk.

d_revalidate can return in rcu-walk mode even when it returns 0. We can't just call any old dcache function on rcu-walk dentry (the dentry is unstable, so even through d_lock can safely be taken, the result may no longer be what we expect -- careful re-checks would be required). So just drop rcu in this case. (I missed this conversion when switching to the rcu-walk convention that Linus suggested) Signed-off-by: NNick Piggin <npiggin@kernel.dk>

In the current implementation mem_cgroup_end_migration() decides whether the page migration has succeeded or not by checking "oldpage->mapping". But if we are tring to migrate a shmem swapcache, the page->mapping of it is NULL from the begining, so the check would be invalid. As a result, mem_cgroup_end_migration() assumes the migration has succeeded even if it's not, so "newpage" would be freed while it's not uncharged. This patch fixes it by passing mem_cgroup_end_migration() the result of the page migration.

In mem_cgroup_alloc() we currently do either kmalloc() or vmalloc() then followed by memset() to zero the memory. This can be more efficiently achieved by using kzalloc() and vzalloc(). There's also one situation where we can use kzalloc_node() - this is what's new in this version of the patch.

Commit b1dd693e ("memcg: avoid deadlock between move charge and try_charge()") can cause another deadlock about mmap_sem on task migration if cpuset and memcg are mounted onto the same mount point. After the commit, cgroup_attach_task() has sequence like: cgroup_attach_task() ss->can_attach() cpuset_can_attach() mem_cgroup_can_attach() down_read(&mmap_sem) (1) ss->attach() cpuset_attach() mpol_rebind_mm() down_write(&mmap_sem) (2) up_write(&mmap_sem) cpuset_migrate_mm() do_migrate_pages() down_read(&mmap_sem) up_read(&mmap_sem) mem_cgroup_move_task() mem_cgroup_clear_mc() up_read(&mmap_sem) We can cause deadlock at (2) because we've already aquire the mmap_sem at (1). But the commit itself is necessary to fix deadlocks which have existed before the commit like: Ex.1) move charge | try charge --------------------------------------+------------------------------ mem_cgroup_can_attach() | down_write(&mmap_sem) mc.moving_task = current | .. mem_cgroup_precharge_mc() | __mem_cgroup_try_charge() mem_cgroup_count_precharge() | prepare_to_wait() down_read(&mmap_sem) | if (mc.moving_task) -> cannot aquire the lock | -> true | schedule() | -> move charge should wake it up Ex.2) move charge | try charge --------------------------------------+------------------------------ mem_cgroup_can_attach() | mc.moving_task = current | mem_cgroup_precharge_mc() | mem_cgroup_count_precharge() | down_read(&mmap_sem) | .. | up_read(&mmap_sem) | | down_write(&mmap_sem) mem_cgroup_move_task() | .. mem_cgroup_move_charge() | __mem_cgroup_try_charge() down_read(&mmap_sem) | prepare_to_wait() -> cannot aquire the lock | if (mc.moving_task) | -> true | schedule() | -> move charge should wake it up This patch fixes all of these problems by: 1. revert the commit. 2. To fix the Ex.1, we set mc.moving_task after mem_cgroup_count_precharge() has released the mmap_sem. 3. To fix the Ex.2, we use down_read_trylock() instead of down_read() in mem_cgroup_move_charge() and, if it has failed to aquire the lock, cancel all extra charges, wake up all waiters, and retry trylock.
