However: (1) It just started showing up # in the wild and (2) Its consequences are dire, so its fix needs to go # in sooner rather than later. # # Testing is of course being upgraded, and the upgraded tests detect # this situation very quickly. But to the best of my knowledge right # now, the tests are not particularly urgent and will thus most likely # show up in the v6.5 merge window (the one after this coming one). # # Kudos to Ziwei Dai and his group for tracking this one down the hard # way!" # # * tag 'urgent-rcu.2023.04.07a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: # rcu/kvfree: Avoid freeing new kfree_rcu() memory after old grace period # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 0d3eb744aed40ffce820cded61d7eac515199165 # < make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # < make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 160 ARCH=m68k O=/kisskb/build/linus_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/m68k-linux/bin/m68k-linux- In file included from /kisskb/src/include/linux/rculist.h:10, from /kisskb/src/include/linux/pid.h:5, from /kisskb/src/include/linux/sched.h:14, from /kisskb/src/fs/btrfs/volumes.c:6: /kisskb/src/fs/btrfs/volumes.c: In function 'btrfs_init_new_device': /kisskb/src/include/linux/list.h:74:19: warning: 'seed_devices' may be used uninitialized in this function [-Wmaybe-uninitialized] 74 | new->prev = prev; | ~~~~~~~~~~^~~~~~ /kisskb/src/fs/btrfs/volumes.c:2621:34: note: 'seed_devices' was declared here 2621 | struct btrfs_fs_devices *seed_devices; | ^~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_m68k-defconfig_m68k-gcc11 # Build took: 0:01:59.206253
