From: Stefano Stabellini Date: Wed, 19 Oct 2016 19:22:35 +0000 (-0700) Subject: vscsiif.h: replace PAGE_SIZE with VSCSIIF_PAGE_SIZE X-Git-Tag: 4.8.0-rc4~11 X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=d93539cc486aa6022195305dbea5fe12f90b69fe;p=xen.git vscsiif.h: replace PAGE_SIZE with VSCSIIF_PAGE_SIZE Do not reference PAGE_SIZE directly: it could be undefined, or it could have different values in the frontend or in the backend. Define VSCSIIF_PAGE_SIZE as 4096, assuming all users of vscsiif.h have 4K page granularity. Replace PAGE_SIZE with VSCSIIF_PAGE_SIZE.
