* 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.

* [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: Add new cluster lock typeMark Fasheh2006-09-24

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 cluster lock type which OCFS2 can attach to dentries. A small number of fs/ocfs2/dcache.c functions are stubbed out so that this change can compile.

* ocfs2: Update dlmglue for new dlmlock() APIMark Fasheh2006-09-24

* ocfs2: Update dlmfs for new dlmlock() APIMark Fasheh2006-09-24

* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | misreports it) Our ATA probe code checks that a device is not reporting a diagnostic failure during start up. Unfortunately at least one device seems to like doing this - the Gigabyte iRAM. This is only done for the master right now (which is fine for the iRAM as it is SATA), as with PATA some combinations of ATAPI device seem to fool the check into seeing a drive that isn't there if it is applied to the slave.

| * | | [PATCH] libata: fix non-uniform ports handlingTejun Heo2006-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Non-uniform ports handling got broken while updating libata to handle those in the same host. Only separate irq for the non-uniform secondary port was implemented while all other fields (host flags, transfer mode...) of the secondary port simply shared those of the first. For ata_piix combined mode, which ATM is the only user of non-uniform ports, this causes the secondary port assume the wrong type. This can cause PATA port to use SATA ops, which results in bogus check on PCS and detection failure. This patch adds ata_probe_ent->pinfo2 which points to optional port_info for the secondary port. For the time being, this seems to be the simplest solution. This workaround will be removed together with ata_probe_ent itself after init model is updated to allow more flexibility.

The result is that this situation : 0100-01fe : pnp 00:09 0170-0177 : libata 01f0-01f7 : libata is seen as conflict, which is wrong. The proposed fix is to detect childs and in this case, look at which child is conflicting. Signed-off-by: Arnaud Patard <apatard@mandriva.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
