CIFS: Add rwpidforward mount option

2011-05-27T03:57:16+00:00

Add rwpidforward mount option that switches on a mode when we forward
pid of a process who opened a file to any read and write operation.

This can prevent applications like WINE from failing on read or write
operation on a previously locked file region from the same netfd from
another process if we use mandatory brlock style.

It is actual for WINE because during a run of WINE program two processes
work on the same netfd - share the same file struct between several VFS
fds:
1) WINE-server does open and lock;
2) WINE-application does read and write.

[CIFS] Migrate from prefixpath logic

2011-05-27T03:50:55+00:00

Now we point superblock to a server share root and set a root dentry
appropriately. This let us share superblock between mounts like
//server/sharename/foo/bar and //server/sharename/foo further.

CIFS: Use pid saved from cifsFileInfo in writepages and set_file_size

2011-05-26T18:07:02+00:00

We need it to make them work with mandatory locking style because
we can fail in a situation like when kernel need to flush dirty pages
and there is a lock held by a process who opened file.

Simplify many places when we call cifs_revalidate/invalidate to make
it do what it exactly needs.

CIFS: Use invalidate_inode_pages2 instead of invalidate_remote_inode (try #4)

2011-05-19T14:10:50+00:00

Use invalidate_inode_pages2 that don't leave pages even if shrink_page_list()
has a temp ref on them. It prevents a data coherency problem when
cifs_invalidate_mapping didn't invalidate pages but the client thinks that a data
from the cache is uptodate according to an oplock level (exclusive or II).
