/*
Commit b3df561fbf has introduced the ability to convert extended inode time precision on ext4, but this breaks builds on older distros, where ext4 does not have the nsec time precision. Commit c615287cc tried to fix that by testing the availability of the EXT4_EPOCH_MASK macro, but the test is not complete. This patch aims at fixing the macro test, and changes the name of the associated HAVE_ macro, since the logic is reverted. This fixes #353 when ext4 has nsec time precision. Note that the test fails when ext4 does not have the nsec time precision. Maybe the test shouldn't be run in that case?
