The migration / DLPAR window close can # hang while trying to acquire mmap lock if it is issued at the # same time with the user space ioctl mmap or VAS fault handler # execution. # # So this patch adds changes to acquire mmap lock before holding # mmap_mutex. # # Fixes: 8ef7b9e1765a ("powerpc/pseries/vas: Close windows with DLPAR core removal") # Signed-off-by: Haren Myneni <haren@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/20230622074246.144729-1-haren@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 36686e99e6e09c4043c34cf0c44f84f1e52f7ac9 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_PERF_EVENTS=n # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_powernv_defconfig+NO_PERF_powerpc-gcc12 # Build took: 0:04:00.992254
