Changes by: antona
Update of /cvsroot/linux-ntfs/linux-ntfs/include
In directory usw-pr-cvs1:/tmp/cvs-serv27230/include
Modified Files:
Makefile.in attrib.h
Log Message:
Hammer out the API for run list merging. Add calls for low level (using raw run lists and ATTR_RECORDs as parameters) run list merging, mappaing pairs decompression, and vcn to lcn conversion as well as high level (using ntfs_attr as parameter) calls for run list mapping and vcn to lcn conversion.
