I have sent this version of the patch series using b4 for the first 
time, as suggested earlier [1]. The issue might be due to the previous 
version being sent
incorrectly using git send-mail. Consequently, I had to manually apply 
the previous patches after creating the b4 branch,
since "b4 prep -F" was throwing an error when trying to apply the last 
patch.
