+Subject: [PATCH 1/2] xfs: fix nfs export of 64-bit inodes numbers on 32-bit
+       kernels
+
+commit c29f7d457ac63311feb11928a866efd2fe153d74 upstream.
+
+The i_ino field in the VFS inode is of type unsigned long and thus can't
+hold the full 64-bit inode number on 32-bit kernels.  We have the full
+inode number in the XFS inode, so use that one for nfs exports.  Note
+that I've also switched the 32-bit file handles types to it, just to make
+the code more consistent and copy & paste errors less likely to happen.

+Subject: [PATCH 2/2] xfs: avoid synchronous transactions when deleting attr
+       blocks
+
+commit 859f57ca00805e6c482eef1a7ab073097d02c8ca upstream.
+
+[slightly different from the upstream version because of a previous cleanup]
+
+Currently xfs_attr_inactive causes a synchronous transactions if we are
+removing a file that has any extents allocated to the attribute fork, and
+thus makes XFS extremely slow at removing files with out of line extended
+attributes. The code looks a like a relict from the days before the busy
+extent list, but with the busy extent list we avoid reusing data and attr
+extents that have been freed but not commited yet, so this code is just
+as superflous as the synchronous transactions for data blocks.
