Merge branch 'for-3.7' of git://linux-nfs.org/~bfields/linux
Pull nfsd update from J Bruce Fields: "Another relatively quiet cycle. There was some progress on my remaining 4.1 todo's, but a couple of them were just of the form "check that we do X correctly", so didn't have much affect on the code. Other than that, a bunch of cleanup and some bugfixes (including an annoying NFSv4.0 state leak and a busy-loop in the server that could cause it to peg the CPU without making progress)." * 'for-3.7' of git://linux-nfs.org/~bfields/linux: (46 commits) UAPI: (Scripted) Disintegrate include/linux/sunrpc UAPI: (Scripted) Disintegrate include/linux/nfsd nfsd4: don't allow reclaims of expired clients nfsd4: remove redundant callback probe nfsd4: expire old client earlier nfsd4: separate session allocation and initialization nfsd4: clean up session allocation nfsd4: minor free_session cleanup nfsd4: new_conn_from_crses should only allocate nfsd4: separate connection allocation and initialization nfsd4: reject bad forechannel attrs earlier nfsd4: enforce per-client sessions/no-sessions distinction nfsd4: set cl_minorversion at create time nfsd4: don't pin clientids to pseudoflavors nfsd4: fix bind_conn_to_session xdr comment nfsd4: cast readlink() bug argument NFSD: pass null terminated buf to kstrtouint() nfsd: remove duplicate init in nfsd4_cb_recall nfsd4: eliminate redundant nfs4_free_stateid fs/nfsd/nfs4idmap.c: adjust inconsistent IS_ERR and PTR_ERR ...

- * This is the new flexible, extensible style NFSv2/v3 file handle.
- * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
- *
- * The file handle starts with a sequence of four-byte words.
- * The first word contains a version number (1) and three descriptor bytes
- * that tell how the remaining 3 variable length fields should be handled.
- * These three bytes are auth_type, fsid_type and fileid_type.
- *
- * All four-byte values are in host-byte-order.
- *
- * The auth_type field specifies how the filehandle can be authenticated
- * This might allow a file to be confirmed to be in a writable part of a
- * filetree without checking the path from it up to the root.
- * Current values:
- * 0 - No authentication. fb_auth is 0 bytes long
- * Possible future values:
- * 1 - 4 bytes taken from MD5 hash of the remainer of the file handle
- * prefixed by a secret and with the important export flags.
- *
- * The fsid_type identifies how the filesystem (or export point) is
- * encoded.
- * Current values:
- * 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
- * NOTE: we cannot use the kdev_t device id value, because kdev_t.h
- * says we mustn't. We must break it up and reassemble.
- * 1 - 4 byte user specified identifier
- * 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
- * 3 - 4 byte device id, encoded for user-space, 4 byte inode number
- * 4 - 4 byte inode number and 4 byte uuid
- * 5 - 8 byte uuid
- * 6 - 16 byte uuid
- * 7 - 8 byte inode number and 16 byte uuid
- *
- * The fileid_type identified how the file within the filesystem is encoded.
- * This is (will be) passed to, and set by, the underlying filesystem if it supports
- * filehandle operations. The filesystem must not use the value '0' or '0xff' and may
- * only use the values 1 and 2 as defined below:
- * Current values:
- * 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes.
- * 1 - 32bit inode number, 32 bit generation number.
- * 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.

+ * This is the new flexible, extensible style NFSv2/v3 file handle.
+ * by Neil Brown <neilb@cse.unsw.edu.au> - March 2000
+ *
+ * The file handle starts with a sequence of four-byte words.
+ * The first word contains a version number (1) and three descriptor bytes
+ * that tell how the remaining 3 variable length fields should be handled.
+ * These three bytes are auth_type, fsid_type and fileid_type.
+ *
+ * All four-byte values are in host-byte-order.
+ *
+ * The auth_type field specifies how the filehandle can be authenticated
+ * This might allow a file to be confirmed to be in a writable part of a
+ * filetree without checking the path from it up to the root.
+ * Current values:
+ * 0 - No authentication. fb_auth is 0 bytes long
+ * Possible future values:
+ * 1 - 4 bytes taken from MD5 hash of the remainer of the file handle
+ * prefixed by a secret and with the important export flags.
+ *
+ * The fsid_type identifies how the filesystem (or export point) is
+ * encoded.
+ * Current values:
+ * 0 - 4 byte device id (ms-2-bytes major, ls-2-bytes minor), 4byte inode number
+ * NOTE: we cannot use the kdev_t device id value, because kdev_t.h
+ * says we mustn't. We must break it up and reassemble.
+ * 1 - 4 byte user specified identifier
+ * 2 - 4 byte major, 4 byte minor, 4 byte inode number - DEPRECATED
+ * 3 - 4 byte device id, encoded for user-space, 4 byte inode number
+ * 4 - 4 byte inode number and 4 byte uuid
+ * 5 - 8 byte uuid
+ * 6 - 16 byte uuid
+ * 7 - 8 byte inode number and 16 byte uuid
+ *
+ * The fileid_type identified how the file within the filesystem is encoded.
+ * This is (will be) passed to, and set by, the underlying filesystem if it supports
+ * filehandle operations. The filesystem must not use the value '0' or '0xff' and may
+ * only use the values 1 and 2 as defined below:
+ * Current values:
+ * 0 - The root, or export point, of the filesystem. fb_fileid is 0 bytes.
+ * 1 - 32bit inode number, 32 bit generation number.
+ * 2 - 32bit inode number, 32 bit generation number, 32 bit parent directory inode number.
