/*
* VOL_CAP_FMT_PERSISTENTOBJECTIDS: When set, the volume has object IDs
* that are persistent (retain their values even when the volume is
* unmounted and remounted), and a file or directory can be looked up
* by ID. Volumes that support VolFS and can support Carbon File ID
* references should set this bit.
*
* VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic
* links. The symlink(), readlink(), and lstat() calls all use this
* symbolic link.
*
* VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links.
* The link() call creates hard links.
*
* VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting
* a journal used to speed recovery in case of unplanned shutdown
* (such as a power outage or crash). This bit does not necessarily
* mean the volume is actively using a journal for recovery.
*
* VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using
* a journal for use in speeding recovery after an unplanned shutdown.
* This bit can be set only if VOL_CAP_FMT_JOURNAL is also set.
*
* VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not
* store reliable times for the root directory, so you should not
* depend on them to detect changes, etc.
*
* VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files.
* That is, files which can have "holes" that have never been written
* to, and are not allocated on disk. Sparse files may have an
* allocated size that is less than the file's logical length.
*
* VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs)
* that have never been written to must appear to contain zeroes. When
* this bit is set, the volume keeps track of allocated but unwritten
* runs of a file so that it can substitute zeroes without actually
* writing zeroes to the media. This provides performance similar to
* sparse files, but not the space savings.
*
* VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are
* case sensitive (upper and lower case are different). When clear,
* an upper case character is equivalent to a lower case character,
* and you can't have two names that differ solely in the case of
* the characters.
*
* VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names
* preserve the difference between upper and lower case. If clear,
* the volume may change the case of some characters (typically
* making them all upper or all lower case). A volume that sets
* VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING.
*
* VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers
* (especially Carbon) that statfs() is fast enough that its results
* need not be cached by those upper layers. A volume that caches
* the statfs information in its in-memory structures should set this bit.
* A volume that must always read from disk or always perform a network
* transaction should not set this bit.
*
* VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports
* file sizes larger than 4GB, and potentially up to 2TB; it does not
* indicate whether the filesystem supports files larger than that.
*
* VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny
* modes (e.g. "open for read write, deny write"; effectively, mandatory
* file locking based on open modes).
*
* VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN
* file flag, and the UF_HIDDEN flag is mapped to that volume's native
* "hidden" or "invisible" bit (which may be the invisible bit from the
* Finder Info extended attribute).
*
* VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability
* to derive a pathname to the root of the file system given only the
* id of an object. This also implies that object ids on this file
* system are persistent and not recycled. This is a very specialized
* capability and it is assumed that most file systems will not support
* it. Its use is for legacy non-posix APIs like ResolveFileIDRef.
*
* VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support
* returning values for total data blocks, available blocks, or free blocks
* (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically,
* those values were set to 0xFFFFFFFF for volumes that did not support them.
*
* VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent
* decompression of compressed files using decmpfs.
*
* VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that
* are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the
* only legitimate attributes for obtaining object IDs from this volume and the
* 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID,
* ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined.
*
* VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory
* hard links.
*
* VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs
* (an ID which persists across object ID changes) for document revisions.
*
* VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write
* generation counts (a count of how many times an object has been modified)
*
* VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support
* setting the UF_IMMUTABLE flag.
*
* VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting
* permissions.
*
* VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with
* other filesystems i.e. multiple logical filesystems can exist in the same
* "partition". An implication of this is that the filesystem which sets
* this capability treats waitfor arguments to VFS_SYNC as bit flags.
*
* VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group
* that implies multiple volumes must be mounted in order to boot and root the
* operating system. Typically, this means a read-only system volume and a
* writable data volume.
*
* VOL_CAP_FMT_SEALED: When set, this volume is cryptographically sealed.
* Any modifications to volume data or metadata will be detected and may
* render the volume unusable.
*
* VOL_CAP_FMT_CLONE_MAPPING: When set, this volume supports full clone tracking.
* See ATTR_CMNEXT_CLONE_REFCNT and ATTR_CMNEXT_CLONEID for more details.
* Other features like extended directory statistics, for fast directory sizing,
* and attribution tags may be supported as well.
* See VOL_CAP_INT_ATTRIBUTION_TAG for more details related to tagging.

/*

* getattrlist() and setattrlist() system calls (vnop_getattrlist

* VOL_CAP_INT_VOL_RENAME: When set, the volume implements the
* ATTR_VOL_NAME attribute for both getattrlist() and setattrlist().
* The volume can be renamed by setting ATTR_VOL_NAME with setattrlist().
*
* VOL_CAP_INT_ADVLOCK: When set, the volume implements POSIX style
* byte range locks via vnop_advlock (accessible from fcntl(2)).
*
* VOL_CAP_INT_FLOCK: When set, the volume implements whole-file flock(2)
* style locks via vnop_advlock. This includes the O_EXLOCK and O_SHLOCK
* flags of the open(2) call.
*
* VOL_CAP_INT_EXTENDED_SECURITY: When set, the volume implements
* extended security (ACLs).
*
* VOL_CAP_INT_USERACCESS: When set, the volume supports the
* ATTR_CMN_USERACCESS attribute (used to get the user's access
* mode to the file).
*
* VOL_CAP_INT_MANLOCK: When set, the volume supports AFP-style
* mandatory byte range locks via an ioctl().
*

* exclusive rename operation.
*

* operations on files that are open.
*
* VOL_CAP_INT_RENAME_SECLUDE: When set, the volume supports a
* seclude rename operation.
*
* VOL_CAP_INT_ATTRIBUTION_TAG: When set, the volume supports establishing
* an owner relationship between a file (excluding small files) and a process
