/* bh state bits */
#define BH_Uptodate 0 /* 1 if the buffer contains valid data */
#define BH_Dirty 1 /* 1 if the buffer is dirty */
#define BH_Lock 2 /* 1 if the buffer is locked */
#define BH_Req 3 /* 0 if the buffer has been invalidated */
#define BH_Protected 6 /* 1 if the buffer is protected */
#define BH_Wait_IO 7 /* 1 if we should throttle on this buffer */
#define BH_Temp 8 /* 1 if the buffer is temporary (unlinked) */
#define BH_JWrite 9 /* 1 if being written to log (@@@ DEBUGGING)*/
#define BH_QuickFree 10 /* 1 if alloced and freed quickly (see below)*/
#define BH_Alloced 11 /* 1 if buffer has been allocated */
#define BH_Freed 12 /* 1 if buffer has been freed (truncated)*/
#define BH_Revoked 13 /* 1 if buffer has been revoked from the log*/
#define BH_RevokeValid 14 /* 1 if buffer revoked flag is valid */
#define BH_JDirty 15 /* 1 if buffer is dirty but journaled */

As you can see, that is already taken from ext3. Is this ok?

#define BH_LowPrio 16 /* 1 if the buffer is temporary (unlinked)

Or do I only have 16 bits to work with?

TIA,

Mike
