     29 // M27: crbug.com/229304, Migration code for this is removed in M34.
     30 //   The "Google Drive" folder is moved from /special/drive to
     31 //   /special/drive/root to stored shared files outside of "My Drive" in
     32 //   /special/drive/other.
     33 //
     34 // M34: crbug.com/313539
     35 //   The "Downloads" folder is changed from /home/chronos/user/Downloads to
     36 //   /home/chronos/u-<hash>/Downloads when multi-profile is enabled.
     37 //
     38 //   The path "/home/chronos/user" is a hard link to the u-<hash> directory of
     39 //   the primary profile of the current session. The two paths always meant the
     40 //   same directory before multi-profiles. However, for secondary profiles in
     41 //   a multi-profile session, the "user" path cannot be used to mean "its own"
     42 //   Download folder anymore. Thus we are switching to always use "u-<hash>"
     43 //   that consistently works whether or not it is primary.
     44 //
     45 // M35: crbug.com/356322
     46 //   It turned out even if multi-profile is disabled, u-<hash> style profile
     47 //   can be used in some situations. To address the cases, we add a migration
     48 //   from /home/chronos/u-<hash>/Downloads to current Download path.
     49 //   This just results in no-op when multi-profile is enabled.
