The new optional mount parm, "acdirmax" allows caching the metadata for a directory longer than file metadata, which can be very helpful for performance. Convert cifs_inode_needs_reval to check acdirmax for revalidating directory metadata.

nfs and cifs on Linux currently have a mount parameter "actimeo" to control metadata (attribute) caching but cifs does not have additional mount parameters to allow distinguishing between caching directory metadata (e.g. needed to revalidate paths) and that for files. Add new mount parameter "acdirmax" to allow caching metadata for directories more loosely than file data. NFS adjusts metadata caching from acdirmin to acdirmax (and another two mount parms for files) but to reduce complexity, it is safer to just introduce the one mount parm to allow caching directories longer. The defaults for acdirmax and actimeo (for cifs.ko) are conservative, 1 second (NFS defaults acdirmax to 60 seconds). For many workloads, setting acdirmax to a higher value is safe and will improve performance. This patch leaves unchanged the default values for caching metadata for files and directories but gives the user more flexibility in adjusting them safely for their workload via the new mount parm.

Static code analysis reported a possible null pointer dereference in my last commit: cifs: Retain old ACEs when converting between mode bits and ACL. This could happen if the DACL returned by the server is corrupted. We were trying to continue by assuming that the file has empty DACL. We should bail out with an error instead.

When cifsacl mount option is used, retain the ACEs which should not be modified during chmod. Following is the approach taken: 1. Retain all explicit (non-inherited) ACEs, unless the SID is one of owner/group/everyone/authenticated-users. We're going to set new ACEs for these SIDs anyways. 2. At the end of the list of explicit ACEs, place the new list of ACEs obtained by necessary conversion/encoding. 3. Once the converted/encoded ACEs are set, copy all the remaining ACEs (inherited) into the new ACL.

Introduced a new field conn_id in TCP_Server_Info structure. This is a non-persistent unique identifier maintained by the client for a connection to a file server. For this, a global counter named tcpSesNextId is maintained. On allocating a new TCP_Server_Info, this counter is incremented and assigned. Changed the dynamic tracepoints related to reconnects and crediting to be more informative (with conn_id printed). Debugging a crediting issue helped me understand the important things to print here. Always call dynamic tracepoints outside the scope of spinlocks. To do this, copy out the credits and in_flight fields of the server struct before dropping the lock.

For failure by timeout waiting for credits, changed the error returned to the app with EBUSY, instead of ENOTSUPP. This is done because this situation is possible even in non-buggy cases. i.e. overloaded server can return 0 credits until done with outstanding requests. And this feels like a better error to return to the app. For cases of zero credits found even when there are no requests in flight, replaced ENOTSUPP with EDEADLK, since we're avoiding deadlock here by returning error.

Currently specifying "vers=3" only requests smb3.0 and smb3.02 but this patch fixes it to also request smb3.1.1 dialect, as it is the newest and most secure dialect and is a "version 3 or later" dialect (the intent of "vers=3").
