...kill PG_checked please :)  Or at least keep it from spreading.

It already spread - ext3 is using it and I think reiser4.  I thought I
had a patch to rename it to PG_misc1 or somesuch, but no.  It's mandate
becomes "filesystem-specific page flag".

You're carrying a patch to stick a flag called PG_fs_misc, but that has the
same value as PG_checked. An extra page flag beyond PG_uptodate, PG_lock
and PG_writeback is required to make readpage through the cache
non-synchronous.

David,

Interesting, have you got a pointer to a full explanation?  Is this about aio?

Regards,

Daniel
