rip-off of Jens io-wq sharing patches allowing multiple io_uring instances to be bound to a single io-wq. The differences are: - io-wq, which we would like to be shared, is passed as io_uring fd - fail, if can't share. IMHO, it's always better to fail fast and loud I didn't tested it after rebasing, but hopefully won't be a problem. p.s. on top of ("io_uring/io-wq: don't use static creds/mm assignments") Pavel Begunkov (2): io-wq: allow grabbing existing io-wq io_uring: add io-wq workqueue sharing fs/io-wq.c | 10 ++++++ fs/io-wq.h | 1 + fs/io_uring.c | 67 +++++++++++++++++++++++++++-------- include/uapi/linux/io_uring.h | 4 ++- 4 files changed, 67 insertions(+), 15 deletions(-) -- 2.24.0
