Hi Alex, Slava, I'm looking at making a ceph_netfs_write_iter() to handle writing to ceph files through netfs. One thing I'm wondering about is the way ceph_write_iter() handles EOLDSNAPC. In this case, it goes back to retry_snap and renegotiates the caps (amongst other things). Firstly, does it actually need to do this? And, secondly, I can't seem to find anything that actually generates EOLDSNAPC (or anything relevant that generates ERESTART). Is it possible that we could get rid of the code that handles EOLDSNAPC? David
