[PATCH v2 0/2] MR5618: mountmgr.sys: Ignore hidden and system volumes on macOS

[Tim Clem (＠tclem)]

Non-"browsable" volumes or those without filesystem mount points are invisible to users and should not be reflected automatically into Wine.

  v2: mountmgr.sys: Do not add drive letters or volumes for macOS volumes without mount paths.

[PATCH v2 1/2] mountmgr.sys: Do not create drive letters or volumes for unbrowsable macOS volumes.

From: Tim Clem <tclem(a)codeweavers.com>

Volumes with kCFURLVolumeIsBrowsableKey set to false are invisible to
users. These are generally system volumes or temporary ones (like
Chrome update disk images) that we should ignore.

[PATCH v2 2/2] mountmgr.sys: Do not add drive letters or volumes for macOS volumes without mount paths.

[Tim Clem]

From: Tim Clem <tclem(a)codeweavers.com>

Mounted volumes that are not represented in the filesystem are system
volumes that we should ignore (e.g. recovery and preboot).
