140 /*
141 * VOL_CAP_FMT_PERSISTENTOBJECTIDS: When set, the volume has object IDs
142 * that are persistent (retain their values even when the volume is
143 * unmounted and remounted), and a file or directory can be looked up
144 * by ID. Volumes that support VolFS and can support Carbon File ID
145 * references should set this bit.
146 *
147 * VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic
148 * links. The symlink(), readlink(), and lstat() calls all use this
149 * symbolic link.
150 *
151 * VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links.
152 * The link() call creates hard links.
153 *
154 * VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting
155 * a journal used to speed recovery in case of unplanned shutdown
156 * (such as a power outage or crash). This bit does not necessarily
157 * mean the volume is actively using a journal for recovery.
158 *
159 * VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using
160 * a journal for use in speeding recovery after an unplanned shutdown.
161 * This bit can be set only if VOL_CAP_FMT_JOURNAL is also set.
162 *
163 * VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not
164 * store reliable times for the root directory, so you should not
165 * depend on them to detect changes, etc.
166 *
167 * VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files.
168 * That is, files which can have "holes" that have never been written
169 * to, and are not allocated on disk. Sparse files may have an
170 * allocated size that is less than the file's logical length.
171 *
172 * VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs)
173 * that have never been written to must appear to contain zeroes. When
174 * this bit is set, the volume keeps track of allocated but unwritten
175 * runs of a file so that it can substitute zeroes without actually
176 * writing zeroes to the media. This provides performance similar to
177 * sparse files, but not the space savings.
178 *
179 * VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are
180 * case sensitive (upper and lower case are different). When clear,
181 * an upper case character is equivalent to a lower case character,
182 * and you can't have two names that differ solely in the case of
183 * the characters.
184 *
185 * VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names
186 * preserve the difference between upper and lower case. If clear,
187 * the volume may change the case of some characters (typically
188 * making them all upper or all lower case). A volume that sets
189 * VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING.
190 *
191 * VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers
192 * (especially Carbon) that statfs() is fast enough that its results
193 * need not be cached by those upper layers. A volume that caches
194 * the statfs information in its in-memory structures should set this bit.
195 * A volume that must always read from disk or always perform a network
196 * transaction should not set this bit.
197 *
198 * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports
199 * file sizes larger than 4GB, and potentially up to 2TB; it does not
200 * indicate whether the filesystem supports files larger than that.
201 *
202 * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny
203 * modes (e.g. "open for read write, deny write"; effectively, mandatory
204 * file locking based on open modes).
205 *
206 * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN
207 * file flag, and the UF_HIDDEN flag is mapped to that volume's native
208 * "hidden" or "invisible" bit (which may be the invisible bit from the
209 * Finder Info extended attribute).
210 *
211 * VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability
212 * to derive a pathname to the root of the file system given only the
213 * id of an object. This also implies that object ids on this file
214 * system are persistent and not recycled. This is a very specialized
215 * capability and it is assumed that most file systems will not support
216 * it. Its use is for legacy non-posix APIs like ResolveFileIDRef.
217 *
218 * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support
219 * returning values for total data blocks, available blocks, or free blocks
220 * (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically,
221 * those values were set to 0xFFFFFFFF for volumes that did not support them.
222 *
223 * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent
224 * decompression of compressed files using decmpfs.
225 *
226 * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that
227 * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the
228 * only legitimate attributes for obtaining object IDs from this volume and the
229 * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID,
230 * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined.
231 *
232 * VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory
233 * hard links.
234 *
235 * VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs
236 * (an ID which persists across object ID changes) for document revisions.
237 *
238 * VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write
239 * generation counts (a count of how many times an object has been modified)
240 *
241 * VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support
242 * setting the UF_IMMUTABLE flag.
243 *
244 * VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting
245 * permissions.
246 *
247 * VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with
248 * other filesystems i.e. multiple logical filesystems can exist in the same
249 * "partition". An implication of this is that the filesystem which sets
250 * this capability treats waitfor arguments to VFS_SYNC as bit flags.
251 *
252 * VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group
253 * that implies multiple volumes must be mounted in order to boot and root the
254 * operating system. Typically, this means a read-only system volume and a
255 * writable data volume.

313 * VOL_CAP_INT_VOL_RENAME: When set, the volume implements the
