We've had several bugs in this area, and the worry # is always that we could be missing some pieces for file types doing # unusual things (recent /dev/tty example comes to mind, userfaultfd # reads installing file descriptors is another fun one... - both of # which need special handling, and I bet it's not the last weird oddity # we'll find). # # With these identical workers, we can have full confidence that we're # never missing anything. That, in itself, is a huge win. Outside of # that, it's also more efficient since we're not wasting space and code # on tracking state, or switching between different states. # # I'm sure we're going to find little things to patch up after this # series, but testing has been pretty thorough, from the usual # regression suite to production. Any issue that may crop up should be # manageable. # # There's also a nice series of further reductions we can do on top of # this, but I wanted to get the meat of it out sooner rather than later. # The general worry here isn't that it's fundamentally broken. Most of # the little issues we've found over the last week have been related to # just changes in how thread startup/exit is done, since that's the main # difference between using kthreads and these kinds of threads. In fact, # if all goes according to plan, I want to get this into the 5.10 and # 5.11 stable branches as well. # # That said, the changes outside of io_uring/io-wq are: # # - arch setup, simple one-liner to each arch copy_thread() # implementation. # # - Removal of net and proc restrictions for io_uring, they are no # longer needed or useful" # # * tag 'io_uring-worker.v3-2021-02-25' of git://git.kernel.dk/linux-block: (30 commits) # io-wq: remove now unused IO_WQ_BIT_ERROR # io_uring: fix SQPOLL thread handling over exec # io-wq: improve manager/worker handling over exec # io_uring: ensure SQPOLL startup is triggered before error shutdown # io-wq: make buffered file write hashed work map per-ctx # io-wq: fix race around io_worker grabbing # io-wq: fix races around manager/worker creation and task exit # io_uring: ensure io-wq context is always destroyed for tasks # arch: ensure parisc/powerpc handle PF_IO_WORKER in copy_thread() # io_uring: cleanup ->user usage # io-wq: remove nr_process accounting # io_uring: flag new native workers with IORING_FEAT_NATIVE_WORKERS # net: remove cmsg restriction from io_uring based send/recvmsg calls # Revert "proc: don't allow async path resolution of /proc/self components" # Revert "proc: don't allow async path resolution of /proc/thread-self components" # io_uring: move SQPOLL thread io-wq forked worker # io-wq: make io_wq_fork_thread() available to other users # io-wq: only remove worker from free_list, if it was there # io_uring: remove io_identity # io_uring: remove any grabbing of context # ... # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 5695e51619745d4fe3ec2506a2f0cd982c5e27a4 # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c: In function 'is1_entry_set': /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: missing braces around initializer [-Wmissing-braces] struct ocelot_vcap_u16 etype = {0};
