This is try 4 of the first wave of the linux pnfs client submission. This fixes some issues seen at the recent bakeathon, and includes fixes noted since the last version was published in Benny's tree. Major changes are: fix problems due to uninitialized flag when using v2/3 fix deadlock caused by free_lseg sleeping properly update stateid, instead of blindly overwriting fix error handler for LAYOUTGET A complete change set can be found at git://linux-nfs.org/~iisaman/linux-pnfs.git, branch devinfo-submit-rc6-needs-squashed For those interested, the patches themselves can also be found under the branch devinfo-submit-rc6-trond A rebase of Benny's pnfs-submit branch onto these patches is under the branch bennys-pnfs-submit-on-devinfo-rc6 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 waves. This first wave 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
