Hi,
When defining DONT_CACHE_MEMORY_OBJECTS in ext2fs.h, a thread can get stuck
in memcpy(), pager/pager-memcpy (called by diskfs/rdwr-internal, called by
io_read). I can provide a gdb trace if someone is interested.
About the purpose of this symbol, I could only find the ChangeLog:
Tue May 9 18:08:41 1995 Miles Bader <[EMAIL PROTECTED]>
* ext2fs.h (DONT_CACHE_MEMORY_OBJECTS): Don't define this any
more, as the bugs we were using it to catch are supposedly gone :-|
Does anybody have any recollections about these bugs?
What effect would have (no) caching of memory objects on the zero hole bug
situation?
Thanks,
Marcus
