This patch implements punch hole (fallocate) support for Ceph kernel file system client. We prepared two patches based on different kernel versions, one against kernel 3.8-rc3, the other against the latest 3.10-rc5. It is because unfortunately, we failed to set up a workable Ceph system with the client based on the lastest code from Linux kernel git tree, for the server side, we tried both the latest code from Ceph git tree and the latest v0.61.3 release. The client will easily hang there without any response, unless rebooting the machine. We managed to set up a Ceph system with the client based on Linux kernel 3.8-rc3 and the server based on Ceph v0.61.3, so the patch against v3.8-rc3 has been under preliminary tests. However, the one against v3.10-rc5 not. Comments are appreciated. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
