Since there are only 19 command codes, it also is easier to track by exact command code than it was for cifs. Signed-off-by: NPavel Shilovsky <pshilovsky@samba.org> Signed-off-by: NSteve French <smfrench@gmail.com>

For SMB2 protocol we can add more than one credit for one received request: it depends on CreditRequest field in SMB2 response header. Also we divide all requests by type: echoes, oplocks and others.

Add mapping table for 32 bit SMB2 status codes to linux errors. Note that SMB2 does not use DOS/OS2 errors (ever) so mapping to DOS/OS2 errors as a common network subset (as we do for cifs) doesn't help. And note that the set of status codes is much more complete here.

Split all requests to echos, oplocks and others - each group uses its own credit slot. This is indicated by new flags CIFS_ECHO_OP and CIFS_OBREAK_OP that are not used now for CIFS. This change is required to support SMB2 protocol because of different processing of these commands.

struct file_lock is pretty large, so we really don't want that on the stack in a potentially long call chain. Reorganize the arguments to CIFSSMBPosixLock to eliminate the need for that. Eliminate the get_flag and simply use a non-NULL pLockInfo to indicate that this is a "get" operation. In order to do that, need to add a new loff_t argument for the start_offset.

Calling key_revoke here isn't ideal as further requests for the key will end up returning -EKEYREVOKED until it gets purged from the cache. What we really intend here is to force a new upcall on the next request_key.

When we get back a FIND_FIRST/NEXT result, we have some info about the dentry that we use to instantiate a new inode. We were ignoring and discarding that info when we had an existing dentry in the cache. Fix this by updating the inode in place when we find an existing dentry and the uniqueid is the same.

This patch fixes this by serializing the marshal_iov operations for async reads and writes. The idea here is to ensure that cifs aggressively tries to populate a request before attempting to fulfill another one. As soon as all of the pages are kmapped for a request, then we can unlock and allow another one to proceed. There's no need to do this serialization on non-CONFIG_HIGHMEM arches however, so optimize all of this out when CONFIG_HIGHMEM isn't set.
