Here is the current queue of patches for v3.0. There are a few things
worth nothing here:
- rbd requests will be a bit larger now (512kb), which should improve
performance
- readahead size is begin set properly, which helps read performance
(but is not the complete solution)
- There was an audit of all d_parent accesses that resulted in a whole
bunch of patches. Basically any d_parent use needs to be proteted by
the parent directory i_mutex or d_lock or suffer the consequences of
a race with rename.
- open intents are fixed
I hope to send this to Linus in a few days. Let me know if you see any
problems here!
Thanks-
