Return to xfs_iops.h CVS log

Up to [Development] / xfs-linux / linux-2.4

This is a two fold change, first it moves the translation
between linux dev_t and kdev_t up the call stack in xfs
and makes the bulk of xfs work in terms of its on disk
dev_t format. It also cleans up a few related chunks of
code.

The other part of the change reworks how we keep the linux
inode contents and the xfs inode fields in sync. A number
of places where we resynced the two have been removed, these
were basically replicating work elsewhere in the filesystem.
We now also ensure that the inode fields are filled in
before calling unlock_new_inode - there used to be a window.
Finally all the code which hooks together the linux inode
and the xfs inode is brought together as a more coherent
whole rather than being scattered around the inode create
path. Most calls to revalidate the linux inode from the
xfs inode are removed.
Remove linvfs_revalidate_core
