+Subject: [PATCH 3/4] xfs: Convert inode numbers to cpu endianity immediately
+ after reading
+
+Currently XFS driver converted inode numbers to native endianity only
+when using them to compute inode position. Although this works, it is
+somewhat confusing. So convert inode numbers when reading them from disk
+structures as every other field.

+Subject: [PATCH 2/4] xfs: Fix termination loop for directory iteration
+
+Directory iteration used wrong position (sizeof wrong structure) for
+termination of iteration inside a directory block. Luckily the position
+ended up being wrong by just 1 byte and directory entries are larger so
+things worked out fine in practice. But fix the problem anyway.
