* [PATCH] wrong thing iounmapped (qla3xxx)Al Viro2006-09-24
| | | | | | | | | | | | ql3xxx_probe() does ioremap and stores result in ->mem_map_registers. On failure exit it does iounmap() of the same thing. OTOH, ql3xxx_remove() does iounmap() of ->mmap_virt_base which is (a) never assigned and (b) never used other than in that iounmap() call.

| | | | | | | | | | | | | | | | | | Allow a lock type to specifiy whether it makes use of the LVB. The only type which does this right now is the meta data lock.

| | | | | | | | | | | | | | Use of the refresh mechanism is lock-type wide, so move knowledge of that to the ocfs2_lock_res_ops structure. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: Remove i_generation from inode lock namesMark Fasheh2006-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: Encode i_generation in the meta data lvbMark Fasheh2006-09-24
| | | | | | | | | | | | | | | | When i_generation is removed from the lockname, this will help us determine whether a meta data lvb has information that is in sync with the local struct inode. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: Free up some space in the lvbMark Fasheh2006-09-24
| | | | | | | | | | | | | | | | lvb_version doesn't need to be a whole 32 bits. Make it an 8 bit field to free up some space. This should be backwards compatible until we use one of the fields, in which case we'd bump the lvb version anyway. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: Remove special casing for inode creation in ocfs2_dentry_attach_lock()Mark Fasheh2006-09-24
| | | | | | | | | | | | | | | | We can't use LKM_LOCAL for new dentry locks because an unlink and subsequent re-create of a name/inode pair may result in the lock still being mastered somewhere in the cluster. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * ocfs2: manually d_move() during ocfs2_rename()Mark Fasheh2006-09-24
| | | | | | | | | | | | | | | | | | | | Make use of FS_RENAME_DOES_D_MOVE to avoid a race condition that can occur during ->rename() if we d_move() outside of the parent directory cluster locks, and another node discovers the new name (created during the rename) and unlinks it. d_move() will unconditionally rehash a dentry - which will leave stale data in the system. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
| * [PATCH] Allow file systems to manually d_move() inside of ->rename()Mark Fasheh2006-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some file systems want to manually d_move() the dentries involved in a rename. We can do this by making use of the FS_ODD_RENAME flag if we just have nfs_rename() unconditionally do the d_move(). While there, we rename the flag to be more descriptive. OCFS2 uses this to protect that part of the rename operation with a cluster lock.

| * ocfs2: Add dentry tracking APIMark Fasheh2006-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the dentry vote mechanism with a cluster lock which covers a set of dentries. This allows us to force d_delete() only on nodes which actually care about an unlink. Every node that does a ->lookup() gets a read only lock on the dentry, until an unlink during which the unlinking node, will request an exclusive lock, forcing the other nodes who care about that dentry to d_delete() it. The effect is that we retain a very lightweight ->d_revalidate(), and at the same time get to make large improvements to the average case performance of the ocfs2 unlink and rename operations. This patch adds the higher level API and the dentry manipulation code. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| * ocfs2: Allow binary names in the DLMMark Fasheh2006-09-24
| | | | | | | | | | | | | | | | The OCFS2 DLM uses strlen() to determine lock name length, which excludes the possibility of putting binary values in the name string. Fix this by requiring that string length be passed in as a parameter. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
