      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.

      [Damien: * Removed zone cache support
               * Removed mapping of discard to reset write pointer command
               * Modified sd_zbc_read_zones to include checks that the
                 device satisfies the kernel constraints
               * Implemeted REPORT ZONES setup and post-processing based
                 on code from Shaun Tancheff <shaun.tancheff@seagate.com>
               * Removed confusing use of 512B sector units in functions

      Pull befs fixes from Luis de Bethencourt:
       "I recently took maintainership of the befs file system [0]. This is
        the first time I send you a git pull request, so please let me know if
        all the below is OK.
      
        Salah Triki and myself have been cleaning the code and fixing a few
        small bugs.
      
        Sorry I couldn't send this sooner in the merge window, I was waiting
        to have my GPG key signed by kernel members at ELCE in Berlin a few
        days ago."
