      sd: Implement support for ZBC devices · 89d94756
      Hannes Reinecke authored
      
      
      Implement ZBC support functions to setup zoned disks, both
      host-managed and host-aware models. Only zoned disks that satisfy
      the following conditions are supported:
      1) All zones are the same size, with the exception of an eventual
         last smaller runt zone.
      2) For host-managed disks, reads are unrestricted (reads are not
         failed due to zone or write pointer alignement constraints).
      Zoned disks that do not satisfy these 2 conditions are setup with
      a capacity of 0 to prevent their use.
      
      The function sd_zbc_read_zones, called from sd_revalidate_disk,
      checks that the device satisfies the above two constraints. This
      function may also change the disk capacity previously set by
      sd_read_capacity for devices reporting only the capacity of
      conventional zones at the beginning of the LBA range (i.e. devices
      reporting rc_basis set to 0).
      
      The capacity message output was moved out of sd_read_capacity into
      a new function sd_print_capacity to include this eventual capacity
      change by sd_zbc_read_zones. This new function also includes a call
      to sd_zbc_print_zones to display the number of zones and zone size
      of the device.

        CPU operation (due to runtime data differences, hardware differences,
        SMP ordering, thermal timing variation, cache behavior, etc).

       "Including:
      
         - nine bug fixes for stable. Some of these we found at the recent two
           weeks of SMB3 test events/plugfests.
      
         - significant improvements in reconnection (e.g. if server or network
           crashes) especially when mounted with "persistenthandles" or to
           server which advertises Continuous Availability on the share.
      
         - a new mount option "idsfromsid" which improves POSIX compatibility
           in some cases (when winbind not configured e.g.) by better (and
           faster) fetching uid/gid from acl (when "cifsacl" mount option is
           enabled). NB: we are almost complete work on "cifsacl" (querying
           mode/uid/gid from ACL) for SMB3, but SMB3 support for cifsacl is
           not included in this set.
      
         - improved handling for SMB3 "credits" (even if server is buggy)
      
        Still working on two sets of changes:
      
         - cifsacl enablement for SMB3
      
         - cleanup of RFC1001 length calculation (so we can handle encryption
           and multichannel and RDMA)
      
        And a couple of new bugs were reported recently (unrelated to above)
        so will probably have another merge request next week"
