Subject: [PATCH] libext2fs: Fix fsync(2) detection
References: bsc#1038194

For some reason lib/ was missing a definition of HAVE_FSYNC
and as a result lib/config.h never had HAVE_FSYNC defined. As a result
we never called fsync(2) for example from
lib/ext2fs/unix_io.c:unix_flush() when we finished creating filesystem
and could miss IO errors happening during creating of the filesystem.
Test generic/405 exposes this problem.

Fix the problem by defining HAVE_FSYNC in lib/
