[PATCH v2 00/46] Lustre IO stack simplifications and cleanups
From: green
Date: Wed Mar 30 2016 - 19:49:46 EST
From: Oleg Drokin <green@xxxxxxxxxxxxxx>
v2 due to a compile error that was accidentally introduced
in one of the patches. Also added a few more fixes and cleanups
as three additional patches at the end of the series.
This large body of patches mostly deals with Lustre IO stack
simplifications and related cleanups.
In particular the whole cl_page and cl_lock stuff is reduced to
basically nothing.
The simplifications remove about 5K lines of code and the other 5k
are mostly due to shuffling code around and renaming stuff
to get rid of now defunct layers.
