Subject: 2.4.14 loopback blk dev compilation trouble

Greetings.
I've seen that the compilation of off-the-server
2.4.14 tree fails at the end of 'make bzImage' because
drivers/block/loop.c uses the deactivate_page() function,
which seems to have been removed from the source tree.
By following the progress of the kernel through
2.4.12, 2.4.13, and 2.4.14 patches, I've seen that
page_cache_release() does the same things as
deactivate_page(). Both these functions are used in the
together twice in drivers/block/loop.c. I compiled
the 2.4.14 kernel by commenting out the references to
deactivate_page() but leaving page_cache_release(), and
loopback block devs work; but I do not have the resources
to check it for memory leaks etc.
I _think_ I've done the right thing, but
would appreciate verification by a regular kernel-
hacker :-)
I searched the net for some reference to this problem,
but couldn't find anything so far.

(I've compiled loop blk-dev support in to the kernel.)

Remove the lines containing deactivate_page() and compilation should go
smoothly. This problem was fixed in 2.4.15-pre1.

This was discussed on this list _many_ times. Wonder how you missed ;)

Cheers,

That's the correct way to correct the compilation problem. It has been
reported 22987432 times already...
