Some applications don't really like # that, so the io_read() code now handles short reads internally, and # got a cleanup along the way so that it's now easier to read (and # documented). We're now passing tests that failed before" # # * tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block: # io_uring: short circuit -EAGAIN for blocking read attempt # io_uring: sanitize double poll handling # io_uring: internally retry short reads # io_uring: retain iov_iter state over io_read/io_write calls # task_work: only grab task signal lock when needed # io_uring: enable lookup of links holding inflight files # io_uring: fail poll arm on queue proc failure # io_uring: hold 'ctx' reference around task_work queue + execute # fs: RWF_NOWAIT should imply IOCB_NOIO # io_uring: defer file table grabbing request cleanup for locked requests # io_uring: add missing REQ_F_COMP_LOCKED for nested requests # io_uring: fix recursive completion locking on oveflow flush # io_uring: use TWA_SIGNAL for task_work uncondtionally # io_uring: account locked memory before potential error case # io_uring: set ctx sq/cq entry count earlier # io_uring: Fix NULL pointer dereference in loop_rw_iter() # io_uring: add comments on how the async buffered read retry works # io_uring: io_async_buf_func() need not test page bit # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 2cc3c4b3c2e9c99e90aaf19cd801ff2c160f283c # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc6xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc6xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc6xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_ppc6xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1667:1: warning: the frame size of 1160 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ In file included from /kisskb/src/kernel/rcu/update.c:591:0: /kisskb/src/kernel/rcu/tasks.h:593:13: warning: 'show_rcu_tasks_classic_gp_kthread' defined but not used [-Wunused-function] static void show_rcu_tasks_classic_gp_kthread(void) { } ^ In file included from /kisskb/src/include/linux/skbuff.h:31:0, from /kisskb/src/include/linux/if_ether.h:19, from /kisskb/src/include/uapi/linux/ethtool.h:19, from /kisskb/src/include/linux/ethtool.h:18, from /kisskb/src/include/linux/netdevice.h:37, from /kisskb/src/drivers/net/ethernet/sfc/net_driver.h:13, from /kisskb/src/drivers/net/ethernet/sfc/ef100.c:12: /kisskb/src/drivers/net/ethernet/sfc/ef100.c: In function 'ef100_pci_parse_continue_entry': /kisskb/src/include/linux/dma-mapping.h:139:25: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define DMA_BIT_MASK(n) (((n) == 64) ?
