[DLM] fix oops in kref_put when removing a lockspace

2006-11-06T14:28:01+00:00

Now that the lockspace struct is freed when the last sysfs object is released
this patch prevents use of that lockspace by sysfs. We attempt to re-get the
lockspace from the lockspace list and fail the request if it has been removed.

[DLM] Fix kref_put oops

2006-11-06T14:01:07+00:00

This patch fixes the recounting on the lockspace kobject. Previously the lockspace was freed while userspace could have had a
reference to one of its sysfs files, causing an oops in kref_put.

Now the lockspace kfree is moved into the kobject release() function

[DLM] fix iovec length in recvmsg

2006-10-20T13:13:10+00:00

I didn't spot that the msg_iovlen was set to 2 if there
were two elements in the iovec but left at zero if not :(

I think this might be why bob was still seeing trouble.

[DLM] fix iovec length in recvmsg

2006-10-12T21:11:33+00:00

The DLM always passes the iovec length as 1, this is wrong when the circular
buffer wraps round.

[GFS2] inode_diet: Replace inode.u.generic_ip with inode.i_private (gfs)

2006-09-28T12:32:24+00:00

The following patches reduce the size of the VFS inode structure by 28 bytes
on a UP x86.  (It would be more on an x86_64 system).  This is a 10% reduction
in the inode size on a UP kernel that is configured in a production mode
(i.e., with no spinlock or other debugging functions enabled; if you want to
save memory taken up by in-core inodes, the first thing you should do is
disable the debugging options; they are responsible for a huge amount of bloat
in the VFS inode structure).

This patch:

The filesystem or device-specific pointer in the inode is inside a union,
which is pretty pointless given that all 30+ users of this field have been
using the void pointer.  Get rid of the union and rename it to i_private, with
a comment to explain who is allowed to use the void pointer.  This is just a
cleanup, but it allows us to reuse the union 'u' for something something where
the union will actually be used.

[DLM] confirm master for recovered waiting requests

2006-09-08T21:00:12+00:00

Fixing the following scenario:
- A request is on the waiters list waiting for a reply from a remote node.
- The request is the first one on the resource, so first_lkid is set.
- The remote node fails causing recovery.
- During recovery the requesting node becomes master.
- The request is now processed locally instead of being a remote operation.
- At this point we need to call confirm_master() on the resource since
  we're certain we're now the master node.  This will clear first_lkid.
- We weren't calling confirm_master(), so first_lkid was not being cleared
  causing subsequent requests on that resource to get stuck.
