Dear Developers, According to git log, ext3 (via ext4 driver) or ext4 non-extent-mapped files are supported for FALLOC_FL_PUNCH_HOLE since Linux 3.9 [1] (incl. bugs), with fixes since 3.16 [2] or stable 3.14+. I hope this qualifies for a simple one-liner mentioned on reporting_bugs page. Best Regards, Michał Mirosław [1] commit 8bad6fc813a3a5300f51369c39d315679fd88c72 [2] commit a93cd4cf86466caa49cfe64607bea7f0bde3f916 -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
