Hi,

This is V5 of the patches.

Changes since V4:

- Added support to clear SGID while setting posix access acl. fuse
  client sends this information in a flag in SETXATTR message. This
  also requires opting in for using SETXATTR V2.

These patches have dependency on fuse kernel patches. So kernel patches
need to be get merged first.

Posting patches anyway, so that patches can get reviewed and tested.

Thanks
Vivek
