storage/posix: changes with respect to cloudsync
Main changes include logic to update iatt buf with file size from extended attributes in posix rather than having this logic in cloudsync xlator. Change-Id: I44f5f8df7a01e496372557fe2f4eff368dbdaa33 fixes: bz#1642168 Signed-off-by: Anuradha Talur <atalur@commvault.com>
