Subject: fallocate: fix build failure with old linux headers
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fac8b4bd78cd0f33cf71f4a8525f2f56b5e6b3f2;p=util-linux

fallocate: fix build failure with old linux headers

If linux/falloc.h does not exist, the build system still enables the
fallocate util, but ultimately fails when it tries to include the
header and use a define from it.
