    👀 maybe another optimisation to do,
  • b
    eventfd isn't super performant
  • b
    but I suspect the answer is "it depends" 😉
  • b
    I just like removing the code that has to schedule the read
  • b
    That'll be nice
  • b
  • b
    posting this here, return status on whether a file/socket/pipe/whatever was ready or not when read/write/send/recv/whatever was initially done on it
  • b
    should be useful for backpressure signaling on writes/sends
  • b
    other stuff in progress is a limit on multishot receives
  • b
    so you can do "recv multishot from this socket, but stop when XX bytes have been received"
  • b
    latter bits are being done by @better-arm-59593, will hopefully see the light of day soonish
  • b
    I need to get back into the groove of writing up the "here's what's new in kernel x.y.z" on the wiki again
  • b
    OSS ftw!
  • c
    so I little thought has cross my mind
  • c
    with the 
    RING_OP_FSYNC
    , is its behaviour the exact same as the syscall? Including the error behaviour
  • b
    it should be identical, yes
  • b
    @quiet-vase-51687 thanks for the ping about the musl CI builds btw. I really appreciate that
  • b
    Never pulled in a Rust toolchain with musl before so this should be interesting to get working
  • b
    oh wow, turns out alpine is terrible
  • b
    Can't even dynamically link to something
  • b
    Oh boy. At least there's docker
  • b
    But, man
  • c
    alpine is indeed terrible!
  • c
    the default musl allocator also sucks pretty hard for anything performance related
  • k
    huh, are you saying dynamic linking isn't supported with alpine?
  • k
    that sounds wrong
  • b

    Copy code

    Hmm seems like musl doesn't support static binaries + dlopen
