The ZFS code is being restructured to act as a library and a stand
alone module. This allows us to leverage most of the existing code
with minimal modification. It also means we need to drop the Solaris
vfs/vnode functions they will be replaced by Linux equivilants and
updated to be Linux friendly.
For the moment we have left ZFS unchanged and it updates many values
as part of the znode. However, some of these values should be set
in the inode. For the moment this is handled by adding a function
called zfs_inode_update() which updates the inode based on the znode.
This is considered a workaround until we can systematically go
through the ZFS code and have it directly update the inode. At
which point zfs_update_inode() can be dropped entirely. Keeping
two copies of the same data isn't only inefficient it's a breeding
ground for bugs.
Remove unneeded bootfs functions. This support shouldn't be required
for the Linux port, and even if it is it would need to be reworked
to integrate cleanly with Linux.
The zfs_check_global_label() function is part of the HAVE_MLSLABEL
support which was previously commented out by a HAVE_ZPL check.
Since we're still deciding what to do about mls labels wrap it
with the preexisting macro to keep it compiled out.
These compiler warnings were introduced when code which was
previously #ifdef'ed out by HAVE_ZPL was re-added for use
by the posix layer. All of the following changes should be
obviously correct and will cause no semantic changes.
This callback is needed for properly accounting the per-uid and per-gid
space usage. Even if we don't have the ZPL, we still need this callback
in order to have proper on-disk ZPL compatibility and to be able to use
Lustre quotas.
Fortunately, the callback doesn't have any ZPL/VFS dependencies so we
can just move it out of #ifdef HAVE_ZPL.
