Fix the deadlock in set_type() while at it: The code called set_irq_chip_and_handler_name() resp. set_irq_chip() from the set_type() callback. That only works on UP and lock debugging disabled. Otherwise it would dead lock on desc->lock. __irq_set_chip_handler_name_locked() avoids that.

2011-03-25block: fix bug with inserting flush requests as sort/mergeJens Axboe1-1/+4
With the introduction of the on-stack plugging, we would assume that any request being inserted was a normal file system request. As flush/fua requires a special insert mode, this caused problems. Fix this up by checking for this in flush_plug_list() and use the appropriate insert mechanism.

First thing we do in writeback_single_inode() is take the i_lock and the last thing we do is drop it.

2011-03-24fs: remove inode_lock from iput_final and prune_icacheDave Chinner5-22/+17
Now that inode state changes are protected by the inode->i_lock and the inode LRU manipulations by the inode_lru_lock, we can remove the inode_lock from prune_icache and the initial part of iput_final(). instead of using the inode_lock to protect the inode during iput_final, use the inode->i_lock instead. This protects the inode against new references being taken while we change the inode state to I_FREEING, as well as preventing prune_icache from grabbing the inode while we are manipulating it. Hence we no longer need the inode_lock in iput_final prior to setting I_FREEING on the inode. For prune_icache, we no longer need the inode_lock to protect the LRU list, and the inodes themselves are protected against freeing races by the inode->i_lock. Hence we can lift the inode_lock from prune_icache as well. Signed-off-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-03-24fs: Lock the inode LRU list separatelyDave Chinner1-9/+30
Introduce the inode_lru_lock to protect the inode_lru list. This lock is nested inside the inode->i_lock to allow the inode to be added to the LRU list in iput_final without needing to deal with lock inversions. This keeps iput_final() clean and neat. Further, where marking the inode I_FREEING and removing it from the LRU, move the LRU list manipulation within the inode->i_lock to keep the list manipulation consistent with iput_final. This also means that most of the open coded LRU list removal + unused inode accounting can now use the inode_lru_list_del() wrappers which cleans the code up further. However, this locking change means what the LRU traversal in prune_icache() inverts this lock ordering and needs to use trylock semantics on the inode->i_lock to avoid deadlocking. In these cases, if we fail to lock the inode we move it to the back of the LRU to prevent spinning on it.

2011-03-24fs: factor inode disposalDave Chinner1-63/+41
We have a couple of places that dispose of inodes. factor the disposal into evict() to isolate this code and make it simpler to peel away the inode_lock from the code. While doing this, change the logic flow in iput_final() to separate the different cases that need to be handled to make the transitions the inode goes through more obvious.

2011-03-24fs: protect inode->i_state with inode->i_lockDave Chinner11-74/+174
Protect inode state transitions and validity checks with the inode->i_lock. This enables us to make inode state transitions independently of the inode_lock and is the first step to peeling away the inode_lock from the code. This requires that __iget() is done atomically with i_state checks during list traversals so that we don't race with another thread marking the inode I_FREEING between the state check and grabbing the reference. Also remove the unlock_new_inode() memory barrier optimisation required to avoid taking the inode_lock when clearing I_NEW. Simplify the code by simply taking the inode->i_lock around the state change and wakeup. Because the wakeup is no longer tricky, remove the wake_up_inode() function and open code the wakeup where necessary.

Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which resulted in build warnings on all architectures that implement their own versions of show_mem(): lib/lib.a(show_mem.o): In function `show_mem': show_mem.c:(.text+0x1f4): multiple definition of `show_mem' arch/sparc/mm/built-in.o:(.text+0xd70): first defined here The fix is to remove __show_mem() and add its argument to show_mem() in all implementations to prevent this breakage. Architectures that implement their own show_mem() actually don't do anything with the argument yet, but they could be made to filter nodes that aren't allowed in the current context in the future just like the generic implementation.
