* A volume that must always read from disk or always perform a network
* transaction should not set this bit.
*
- * VOL_CAP_FMT_2TB_FILESIZE: When set, the volume format supports file
- * size upto 2TB. This bit does not necessarily mean that the file
- * system does not support file size more than 2TB. This bit does
- * not mean that the currently available space on the volume is 2TB.
+ * 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.
