Hi,

Please consider pulling the following GFS2 fixes....

Steve.

--------------------------------------------------------------------------

Here are three GFS2 fixes for the current kernel tree. These are all related to the block reservation code which was added at the merge window. That code will be getting an update at the forthcoming merge window too. In the mean time though there are a few smaller issues which should be fixed.

The first patch resolves an issue with write sizes of greater than 32 bits with the size hinting code. The second ensures that the allocation data structure is initialised when using xattrs and the third takes into account allocations which may have been made by other nodes which affect a reservation on the local node.

The following changes since commit 0d7614f09c1ebdbaa1599a5aba7593f147bf96ee:

Linux 3.6-rc1 (2012-08-02 16:38:10 -0700)

are available in the git repository at:

GFS2: Make write size hinting code common
GFS2: Fix missing allocation data for set/remove xattr
GFS2: Take account of blockages when using reserved blocks

GFS2: Pull request (merge window)

Hi,

Please consider pulling the following changes,

Steve.

-----------------------------------------------------------------------

The major feature this time is the "rbm" conversion in the resource group code. The new struct gfs2_rbm specifies the location of an allocatable block in (resource group, bitmap, offset) form. There are a number of added helper functions, and later patches then rewrite some of the resource group code in terms of this new structure. Not only does this give us a nice code clean up, but it also removes some of the previous restructions where extents could not cross bitmap boundaries, for example.

In addition to that, there are a few bug fixes and clean ups, but the rbm work is by far the majority of this patch set in terms of number of changed lines.
