    hfsplus: Don't clear SGID when inheriting ACLs · 5cf84432

    commit 84969465 upstream.
    
    When new directory 'DIR1' is created in a directory 'DIR0' with SGID bit
    set, DIR1 is expected to have SGID bit set (and owning group equal to
    the owning group of 'DIR0'). However when 'DIR0' also has some default
    ACLs that 'DIR1' inherits, setting these ACLs will result in SGID bit on
    'DIR1' to get cleared if user is not member of the owning group.
    
    Fix the problem by creating __hfsplus_set_posix_acl() function that does
    not call posix_acl_update_mode() and use it when inheriting ACLs. That
    prevents SGID bit clearing and the mode has been properly set by
    posix_acl_create() anyway.
