- * dev.c -- low level operations on device (storage device)
- *
- * Kern Sibbald, MM
- *
- * NOTE!!!! None of these routines are reentrant. You must
- * use lock_device() and unlock_device() at a higher level,
- * or use the xxx_device() equivalents. By moving the
- * thread synchronization to a higher level, we permit
- * the higher level routines to "seize" the device and
- * to carry out operations without worrying about who
- * set what lock (i.e. race conditions).
- *
- * Note, this is the device dependent code, and may have
- * to be modified for each system, but is meant to
- * be as "generic" as possible.
- *
- * The purpose of this code is to develop a SIMPLE Storage
- * daemon. More complicated coding (double buffering, writer
- * thread, ...) is left for a later version.
- *
- * Unfortunately, I have had to add more and more complication
- * to this code. This was not foreseen as noted above, and as
- * a consequence has lead to something more contorted than is
- * really necessary -- KES. Note, this contortion has been
- * corrected to a large extent by a rewrite (Apr MMI).
