Subject: LU-1606 api: Move defines from lustre_idl.h to lustre_user.h
X-Git-Tag: 2.2.92~19
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=8a06a00535b929a8b5761764457be03a3308f6ec;p=fs%2Flustre-release.git

LU-1606 api: Move defines from lustre_idl.h to lustre_user.h

Move some defines that user's require to be able to use
the api's get_stripe functions.  Since lustre_user.h is the
place designated in lustre_idl.h as the place for definitions
needed both in the IDL and in user space, and since lustre_idl.h
will not compile in user space, it seems logical to relocate
these definitions there.
