Hi Steve,
This series contains reparse point fixes and improvements for SMB2+:
- Add support for creating character/block devices, sockets and fifos
via NFS reparse points by default.
- Add support for creating SMB symlinks via IO_REPARSE_TAG_SYMLINK
reparse points.
- smb2_compound_op()
* allow up to MAX_COMPOUND(5) commands in a single compound request
* introduce SMB2_OP_{GET,SET}_REPARSE commands
- Optimisations for dentry revalidation and read/write of reparse
points by reducing number of roundtrips.
- Fix renaming and hardlinking of reparse points
For people who pass 'mfsymlinks' and 'sfu' mount options, the
implementation is expected to avoid creating reparse points at all.
Volker Lendecke had suggested trying to create both SMB symlink and
mfsymlink in a single compound request but this series doesn't have
it. It could be implemented later.
