Subject: xfs_io: fix gcc-7 related printf warnings
X-Git-Tag: v4.15.0-rc1~142
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=41198ef1fb91af4dba7142c3169d4e06c5e2dbc3;p=thirdparty%2Fxfsprogs-dev.git

xfs_io: fix gcc-7 related printf warnings

New compiler, new checks, new warnings.

Fix the new [-Wformat-truncation=] warnings that io/fsmap.c is
throwing w/ gcc-7.2 because "%lld..%lld" requires a buffer 40
characters long, not 32.
