[DLM] fix oops in kref_put when removing a lockspace

2006-11-06T14:28:01Z

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. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] Fix kref_put oops

2006-11-06T14:01:07Z

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 Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] fix iovec length in recvmsg

2006-10-20T13:13:10Z

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. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

[DLM] fix iovec length in recvmsg

2006-10-12T21:11:33Z

The DLM always passes the iovec length as 1, this is wrong when the circular buffer wraps round. Signed-Off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse

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

2006-09-28T12:32:24Z

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

2006-09-08T21:00:12Z

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.
