hfsplus: add necessary declarations for POSIX ACLs support
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.
