[patch 24/52] fs: dcache reduce d_parent locking
Use RCU property of dcache to simplify locking in some places where we take d_parent and d_lock. Comment: don't need rcu_deref because we take the spinlock and recheck it.

[patch 02/52] fs: fix superblock iteration race
list_for_each_entry_safe is not suitable to protect against concurrent modification of the list. 6754af6 introduced a race in sb walking. list_for_each_entry can use the trick of pinning the current entry in the list before we drop and retake the lock because it subsequently follows cur->next. However list_for_ea... 23 Jun 2010 23:52

[patch 20/52] fs: dcache reduce dcache_inode_lock
dcache_inode_lock can be avoided in d_delete() and d_materialise_unique() in cases where it is not required.

[patch 25/52] fs: dcache DCACHE_REFERENCED improve
dentry referenced bit is only set when installing the dentry back onto the LRU. However with lazy LRU, the dentry can already be on the LRU list at dput time, thus missing out on setting the referenced bit. Fix this.

[RFC 2/5] NMI return notifier
Many kernel services can not be used in NMI handler. So NMI handler needs a mechanism to do these operations in other contexts such as IRQ and process. This patch implements such a mechanism based on soft_irq in a similar way as user return notifier. A new soft_irq named NMI_RETURN_NOTIFIER_SOFTIRQ is defined an... 23 Jun 2010 23:52
