From: Luk Claes Date: Mon, 3 Oct 2011 12:42:20 +0000 (-0400) Subject: blkmapd: Use getconf(_SC_PAGE_SIZE) X-Git-Tag: nfs-utils-1-2-6-rc1~1 X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=fdc6e7eceb6db19bbab7928581f22ba87f257ea4;hp=fef991230b6a4070e0793adf03d42514639111d3 blkmapd: Use getconf(_SC_PAGE_SIZE) PAGE_SIZE is not exported by all architectures as it is not fixed: it can depend on the model of the machine. So it's better to query the system configuration for the actual page size on the machine.
