Description Pranith Kumar K 2019-08-09 10:02:42 UTC 
+++ This bug was initially created as a clone of Bug #1733935 +++

Description of problem:
    Problem:
    when a file needs to be re-opened O_APPEND and O_EXCL
    flags are not filtered in EC.
    
    - O_APPEND should be filtered because EC doesn't send O_APPEND below EC for
    open to make sure writes happen on the individual fragments instead of at the
    end of the file.
    
    - O_EXCL should be filtered because shd could have created the file so even
    without O_EXCL open should succeed.
    
    Fix:
    Filter out these two flags in reopen.
