[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.

I have that patch in my stack but didn't send it; for some reason I
thought it was already changed in your git tree.

Argh, sorry about that... when I fixed these a long time ago they somehow
never got included in the quilt patches.  I mistakenly assumed the quilt
patches matched the source I had in front of me.

[DLM] The core of the DLM for GFS2/CLVM

2006-01-18T09:30:29+00:00

This is the core of the distributed lock manager which is required
to use GFS2 as a cluster filesystem. It is also used by CLVM and
can be used as a standalone lock manager independantly of either
of these two projects.

It implements VAX-style locking modes.
