    This patchset implements POSIX ACLs support in hfsplus driver.
    
    Mac OS X beginning with version 10.4 ("Tiger") support NFSv4 ACLs, which
    are part of the NFSv4 standard.  HFS+ stores ACLs in the form of
    specially named extended attributes (com.apple.system.Security).
    
    But this patchset doesn't use "com.apple.system.Security" extended
    attributes.  It implements support of POSIX ACLs in the form of extended
    attributes with names "system.posix_acl_access" and
    "system.posix_acl_default".  These xattrs are treated only under Linux.
    POSIX ACLs doesn't mean something under Mac OS X.  Thereby, this patch
    set provides opportunity to use POSIX ACLs under Linux on HFS+
    filesystem.
    
    This patch:
    
    Add CONFIG_HFSPLUS_FS_POSIX_ACL kernel configuration option, DBG_ACL_MOD
    debugging flag and acl.h file with declaration of essential functions
    for support POSIX ACLs in hfsplus driver.
