2.5.68-bk10 blkmtd.c:219: warning: implicit declaration of function `alloc_kiovec'

Well, "burned" on ieee1394 i will not try to patch it my self :) Anyway, i can live without those drivers :)

I've tried to investigate this. What happend to iobuf.{ch} ? I guess bit more changes are required to make it running before 2.6 :)

Btw, authors email in head of blkmtd.c is bad.

Fanny thing, after removing this include there is declaration :

/* readpage() - reads one page from the block device */
static int blkmtd_readpage(mtd_raw_dev_data_t *rawdevice, struct page *page) {
int err;
int sectornr, sectors, i;

  struct kiobuf *iobuf;
	^^^^^^^

unsigned long *blocks;

Fast fgrep in kernel sources gives me no answer about this structure declaration.

any help guys ?

blkmtd died when kiobufs were removed. The maintainer said "oh well, OK, I need to rewrite it anyway" but that obviously has not yet happened.

:/

So why we still have this in kernel ?
I don't have any of those devices, so i am not even able to correct this. If i will have, i will do so (at least try).

I hope that is the only case, when somebody leaves project this way.

Waiting for the maintainer to fix it up.

All it needs is a disk drive:

* blkmtd.c - use a block device as a fake MTD

There's a new blkmtd in the MTD CVS.

David:
What are your current plans regarding merging the MTD CVS into 2.5?
