127  * ntfs_volume_alloc - Create an NTFS volume object and initialise it
165  * __ntfs_volume_release - Destroy an NTFS volume object
245  * ntfs_mft_load - load the $MFT and setup the ntfs volume with it
246  * @vol:	ntfs volume whose $MFT to load
249  * volume @vol is ready for use by all read access functions provided by the
411 	 * The volume is now setup so we can use all read access functions.
438  * ntfs_mftmirr_load - load the $MFTMirr and setup the ntfs volume with it
439  * @vol:	ntfs volume whose $MFTMirr to load
442  * the volume @vol is ready for use by all write access functions provided by
490  * ntfs_volume_startup - allocate and setup an ntfs volume
495  * calling this function, the volume is setup sufficiently to call all read

606 	 * beginning of the volume as well. This is in order to protect the

622 	 * halving the zone size until we are inside the volume.
673  * ntfs_volume_check_logfile - check logfile on target volume
674  * @vol:	volume on which to check logfile
733  * @vol:    An ntfs volume obtained from ntfs_mount

921  * This function mounts an ntfs volume. @dev should describe the device which
