This fixes various issue brought up in comments to the previous version. Among the more substantial changes: find_pnfs_driver now grabs module reference driver init/uninit_mountpoint argument changed to struct nfs_server io_ops moved into pnfs_layoutdriver_type handling of pnfs_layout_from_open_stateid changed file driver no longer uses vmalloc deviceid moved from general to driver layer CONFIG_PNFS_FILE_LAYOUT removed, just uses CONFIG_NFS_V4_1 error handling of LAYOUTGET and GETDEVICEINFO rpc calls changed For those interested, the patches can also be found at git://linux-nfs.org/~iisaman/linux-pnfs.git, under the branch devinfo-submit-rc4-trond A rebase of Benny's pnfs-submit branch onto these patches is under the branch bennys-pnfs-submit-on-devinfo-rc4 Fred This is the start of code implementing pnfs, based on RFC 5661. Since sending the whole thing at once would be overwhelming, we are trying to break it into bite sized chunks. This chunk implements the mount/umount infrastructure, as well as sending the LAYOUTGET and GETDEVTICEINFO calls on io (but not actually using the information for io). Note that two major simplifications to the protocol will be made throughout the initial submission process: only the file layout driver is considered, and only whole file layouts are requested. These patches apply against Trond's nfs-for-2.6.37 branch. patches 01-08 implement the mount/umount hooks patches 09-12 implement LAYOUTGET and GETDEVICEINFO -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
