They have been active in development and plan to # switch from virtio-9p to virtio-fs as their default solution. There # has been interest from other sources as well. # # The userspace infrastructure is slated to be merged into qemu once the # kernel part hits mainline. # # This was developed by Vivek Goyal, Dave Gilbert and Stefan Hajnoczi" # # * tag 'virtio-fs-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: # virtio-fs: add virtiofs filesystem # virtio-fs: add Documentation/filesystems/virtiofs.rst # fuse: reserve values for mapping protocol # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-ld --version # < git log --format=%s --max-count=1 8f744bdee4fefb17fac052c7418b830de2b59ac8 # < make -s -j 120 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 120 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=s390 O=/kisskb/build/linus_s390-allmodconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- /kisskb/src/kernel/events/ring_buffer.c: In function 'perf_output_begin_forward': /kisskb/src/kernel/events/ring_buffer.c:269:1: warning: 'perf_output_begin_forward' uses dynamic stack allocation [enabled by default] /kisskb/src/kernel/events/ring_buffer.c: In function 'perf_output_begin_backward': /kisskb/src/kernel/events/ring_buffer.c:275:1: warning: 'perf_output_begin_backward' uses dynamic stack allocation [enabled by default] /kisskb/src/kernel/events/ring_buffer.c: In function 'perf_output_begin': /kisskb/src/kernel/events/ring_buffer.c:283:1: warning: 'perf_output_begin' uses dynamic stack allocation [enabled by default] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] In file included from /kisskb/src/include/linux/uaccess.h:11:0, from /kisskb/src/include/linux/crypto.h:21, from /kisskb/src/include/crypto/hash.h:11, from /kisskb/src/include/linux/uio.h:10, from /kisskb/src/include/linux/socket.h:8, from /kisskb/src/include/linux/skbuff.h:20, from /kisskb/src/include/linux/if_ether.h:19, from /kisskb/src/arch/s390/include/asm/diag.h:12, from /kisskb/src/arch/s390/include/asm/kvm_para.h:25, from /kisskb/src/include/uapi/linux/kvm_para.h:36, from /kisskb/src/include/linux/kvm_para.h:5, from /kisskb/src/include/linux/kvm_host.h:32, from /kisskb/src/arch/s390/kvm/kvm-s390.c:23: /kisskb/src/arch/s390/include/asm/uaccess.h: In function '__put_user_fn': /kisskb/src/arch/s390/include/asm/uaccess.h:113:2: warning: 'rc' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/s390/include/asm/uaccess.h: In function '__get_user_fn': /kisskb/src/arch/s390/include/asm/uaccess.h:143:2: warning: 'rc' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/afs/dynroot.c: In function 'afs_lookup_atcell': /kisskb/src/fs/afs/dynroot.c:124:6: warning: 'len' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/android/binderfs.c: In function 'binderfs_fill_super': /kisskb/src/drivers/android/binderfs.c:657:9: warning: missing braces around initializer [-Wmissing-braces] /kisskb/src/drivers/android/binderfs.c:657:9: warning: (near initialization for 'device_info.name') [-Wmissing-braces] /kisskb/src/ipc/mqueue.c:848:1: internal compiler error: unspellable token PRAGMA Please submit a full bug report, with preprocessed source if appropriate.
