[RFC PATCH 0/4] Rearrange code to make the code more readable

[Chandra Seetharaman <sekharan@xxxxxxxxxx>]

Hello All,

These are the split up patches from patch 1/5 that I posted today, as
suggested by Christoph.

These define some new inline functions and macros, rearrange
the code for easier reading, simplification of code paths
and prepare for the changes to support pquota and gquota
simultaneously.

Regards,
