...rs with b_count == 0 and not dirty), which must conflict somehow with what jfs expects of the state of a buffer. It seems we would not have this problem if bh->b_count was non-zero. What I'm just testing is checking if a buffer is B_FREE before calling refile_buffer() on it, and just doing journal_remove_checkpoint() on the buffer directly... Nope, still not enough - now I get an oops: [[[LVM is in the process of calling PV_FLUSH ioctl => invalidate_buffers()]]] Attempt to refile free buffer Unable to handle kernel NULL pointer dereference at virtual address 00000000 <kdb stuff> refile_buffer journ...

I have ext3 0.0.6b + 2.2.19 and cannot get ext3 to compile as a module. If I try to modularize it, or turn in off completely, the kernel build fails. Is there an easy fix for this, or is there something that I am missing? Thanks. Peter
