+/*
+ * 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: 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_INT_ADVLOCK: When set, the volume implements POSIX style

+ * VOL_CAP_INT_FLOCK: When set, the volume implements whole-file flock(2)
