net/9p: clarify trans_fd parse_opt failure handling (2022-10-07 21:23:09 +0900)

----------------------------------------------------------------
9p-for-6.1: smaller buffers for small messages and fixes

The highlight of this PR is Christian's patch to allocate smaller buffers
for most metadata requests: 9p with a big msize would try to allocate large
buffers when just 4 or 8k would be more than enough; this brings in nice
performance improvements.

There's also a few fixes for problems reported by syzkaller (thanks to
Schspa Shi, Tetsuo Handa for tests and feedback/patches) as well as some
minor cleanup

----------------------------------------------------------------
Christian Schoenebeck (5):
net/9p: split message size argument into 't_size' and 'r_size' pair
9p: add P9_ERRMAX for 9p2000 and 9p2000.u
net/9p: add p9_msg_buf_size()
net/9p: add 'pooled_rbuffers' flag to struct p9_trans_module
net/9p: allocate appropriate reduced message buffers

Dominique Martinet (2):
9p: trans_fd/p9_conn_cancel: drop client lock earlier
net/9p: use a dedicated spinlock for trans_fd

Li Zhong (1):
net/9p: clarify trans_fd parse_opt failure handling

Tetsuo Handa (1):
9p/trans_fd: always use O_NONBLOCK read/write

Xiu Jianfeng (1):
net/9p: add __init/__exit annotations to module init/exit funcs
