[PATCH v2 0/3] hfsplus: introduce functionality of attributes file creation

[Vyacheslav Dubeyko]

Hi,

This is second version of the AttributesFile creation patchset.

v1->v2
* SETOFFSET macro was removed (Andrew Morton).
* Record offsets logic was reworked in hfsplus_init_header_node() (Al Viro).
* AttributesFile's header node's bitmap is initialized by memset() (Al Viro).
* Logic of checking attributes tree state before AttributesFile
  creation was reworked for HFSPLUS_CREATING_ATTR_TREE case (Andrew Morton).
* Setting error code was added after read_mapping_page()
  call in hfsplus_create_attributes_file() method (Andrew Morton).

There are situation when HFS+ volume had been created without
AttributesFile. Such situation can take place because of using
old mkfs.hfs utility or creation HFS+ volume without taking
in mind necessity to use xattrs. For example, Mac OS X 10.4
(Tiger) doesn't create AttributesFile during mkfs phase. Also
it is a very frequent situation for the case of users that
created HFS+ volumes under Linux. As a result, xattrs and
POSIX ACLs on HFS+ volume are unavailable for such users.

This patch set implements functionality of AttributesFile
creation on HFS+ volume in the case of this metadata file
absence during operation of xattr creation.

With the best regards,
Vyacheslav Dubeyko.
