Sorry. By mistake the bug got filed before I filled up description. 

Description of problem:

In case if there is open() done on a file with O_TRUNC posix flag passed, the backend server truncates the file, resulting in change of size of the file. This case needs to be handled by md-cache and should invalidate its cache-entry accordingly.

Patch posted upstream for review -

As discussed with Soumya, executed pynfs test suite with latest build and the OPEN test is passed without any issues.

Moving the BZ to verified.
