I also support some problem in the 0.23pre4 page cache support code, I 
have my own filesystem and experience page cache oops() after using 
dirty shared mmap pages (calling to writepage() fs methods). I think it 
is wise to take out the pagecache support code, at least a compile time 
flag to turn on/off . This will simply way of debugging.
