Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs: net/9p: Fix the msize calculation. fs/9p: add 9P2000.L unlinkat operation fs/9p: add 9P2000.L renameat operation fs/9p: Always ask new inode in create fs/9p: Clean-up get_protocol_version() to use strcmp fs/9p: Fix invalid mount options/args fs/9p: When doing inode lookup compare qid details and inode mode bits. fs/9p: Fid is not valid after a failed clunk. net/9p: Remove structure not used in the code VirtIO can transfer VIRTQUEUE_NUM of pages. Fix the size of receive buffer packing onto VirtIO ring. 9p: clean up packet dump code fs/9p: remove rename work around in 9p net/9p: fix client code to fail more gracefully on protocol error
