142 /*
143  * VOL_CAP_FMT_PERSISTENTOBJECTIDS: When set, the volume has object IDs
144  * that are persistent (retain their values even when the volume is
145  * unmounted and remounted), and a file or directory can be looked up
146  * by ID.  Volumes that support VolFS and can support Carbon File ID
147  * references should set this bit.
148  *
149  * VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic
150  * links.  The symlink(), readlink(), and lstat() calls all use this
151  * symbolic link.
152  *
153  * VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links.
154  * The link() call creates hard links.
155  *
156  * VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting
157  * a journal used to speed recovery in case of unplanned shutdown
158  * (such as a power outage or crash).  This bit does not necessarily
159  * mean the volume is actively using a journal for recovery.
160  *
161  * VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using
162  * a journal for use in speeding recovery after an unplanned shutdown.
163  * This bit can be set only if VOL_CAP_FMT_JOURNAL is also set.
164  *
165  * VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not
166  * store reliable times for the root directory, so you should not
167  * depend on them to detect changes, etc.
168  *
169  * VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files.
170  * That is, files which can have "holes" that have never been written
171  * to, and are not allocated on disk.  Sparse files may have an
172  * allocated size that is less than the file's logical length.
173  *
174  * VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs)
175  * that have never been written to must appear to contain zeroes.  When
176  * this bit is set, the volume keeps track of allocated but unwritten
177  * runs of a file so that it can substitute zeroes without actually
178  * writing zeroes to the media.  This provides performance similar to
179  * sparse files, but not the space savings.
180  *
181  * VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are
182  * case sensitive (upper and lower case are different).  When clear,
183  * an upper case character is equivalent to a lower case character,
184  * and you can't have two names that differ solely in the case of
185  * the characters.
186  *
187  * VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names
188  * preserve the difference between upper and lower case.  If clear,
189  * the volume may change the case of some characters (typically
190  * making them all upper or all lower case).  A volume that sets
191  * VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING.
192  *
193  * VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers
194  * (especially Carbon) that statfs() is fast enough that its results
195  * need not be cached by those upper layers.  A volume that caches
196  * the statfs information in its in-memory structures should set this bit.
197  * A volume that must always read from disk or always perform a network
198  * transaction should not set this bit.
199  *
200  * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports
201  * file sizes larger than 4GB, and potentially up to 2TB; it does not
202  * indicate whether the filesystem supports files larger than that.
203  *
204  * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny
205  * modes (e.g. "open for read write, deny write"; effectively, mandatory
206  * file locking based on open modes).
207  *
208  * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN
209  * file flag, and the UF_HIDDEN flag is mapped to that volume's native
210  * "hidden" or "invisible" bit (which may be the invisible bit from the
211  * Finder Info extended attribute).
212  *
213  * VOL_CAP_FMT_PATH_FROM_ID:  When set, the volume supports the ability
214  * to derive a pathname to the root of the file system given only the
215  * id of an object.  This also implies that object ids on this file
216  * system are persistent and not recycled.  This is a very specialized
217  * capability and it is assumed that most file systems will not support
218  * it.  Its use is for legacy non-posix APIs like ResolveFileIDRef.
219  *
220  * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support
221  * returning values for total data blocks, available blocks, or free blocks
222  * (as in f_blocks, f_bavail, or f_bfree in "struct statfs").  Historically,
223  * those values were set to 0xFFFFFFFF for volumes that did not support them.
224  *
225  * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent
226  * decompression of compressed files using decmpfs.
227  *
228  * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that
229  * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the
230  * only legitimate attributes for obtaining object IDs from this volume and the
231  * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID,
232  * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined.
233  *
234  * VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory
235  * hard links.
236  *
237  * VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs
238  * (an ID which persists across object ID changes) for document revisions.
239  *
240  * VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write
241  * generation counts (a count of how many times an object has been modified)
242  *
243  * VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support
244  * setting the UF_IMMUTABLE flag.
245  *
246  * VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting
247  * permissions.
248  *
249  * VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with
250  * other filesystems i.e. multiple logical filesystems can exist in the same
251  * "partition". An implication of this is that the filesystem which sets
252  * this capability treats waitfor arguments to VFS_SYNC as bit flags.
253  *
254  * VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group
255  * that implies multiple volumes must be mounted in order to boot and root the
256  * operating system. Typically, this means a read-only system volume and a
257  * writable data volume.
258  *
259  * VOL_CAP_FMT_SEALED: When set, this volume is cryptographically sealed.
260  * Any modifications to volume data or metadata will be detected and may
261  * render the volume unusable.
262  *
263  * VOL_CAP_FMT_CLONE_MAPPING: When set, this volume supports full clone tracking.
264  * See ATTR_CMNEXT_CLONE_REFCNT and ATTR_CMNEXT_CLONEID for more details.
265  * Other features like extended directory statistics, for fast directory sizing,
266  * and attribution tags may be supported as well.
267  * See VOL_CAP_INT_ATTRIBUTION_TAG for more details related to tagging.
