[lustre-devel] [PATCH RFC 00/28] lustre: PFL port to linux client

[James Simmons]

This is the initial PFL port to the linux lustre client. This opens
up feed back on the port so far. Currently sanity passes but the
test for sanity-pfl fail as below. I have been tracking downing
various bugs but this one remains and I haven't found out why its
failing. So far from what I can tell is lov_io_setattr_iter_init()
it returning -ENODATA due to lsm_entry_inited() is not initialized.
Hoping that sending this out more eyes might help to see where this
last problem is.
