Aneesh Kumar K.V df5d8c80f1 9p: revert tsyncfs related changes
Now that we use write_inode to flush server
cache related to fid, we don't need tsyncfs either fort dotl or dotu
protocols. For dotu this helps to do a more efficient server flush.

Aneesh Kumar K.V 059c138bc7 fs/9p: Use truncate_setsize instead of vmtruncate
convert vmtruncate usage to truncate_setsize. We also writeback
all dirty pages before doing 9p operations and on success call truncate_setsize.
This ensure that we continue sanely on failed truncate on the server. The
disadvantage is that we are now going to write back the content that get
thrown away later as a part of truncate.

Venkateswararao Jujjuri (JV) e782ef7109 [fs/9P] Add posixacl mount option
The mount option access=client is overloaded as it assumes acl too.
Adding posixacl option to enable POSIX ACLs makes it explicit and clear.
Also it is convenient in the future to add other types of acls like richacls.

Ideally, the access mode 'client' should be just like V9FS_ACCESS_USER
except it underscores the location of access check.
Traditional 9P protocol lets the server perform access checks but with
this mode, all the access checks will be performed on the client itself.
Server just follows the client's directive.

With create/mkdir/mknod in non cached mode we initialize the inode using
v9fs_get_inode. v9fs_get_inode doesn't initialize the cache inode value

Fix is to initialize acls to NULL and not to leave them in ACL_NOT_CACHED
state.
