In the rare case where kernel find all the # 8 primary hash slot occupied by bolted entries, this can result in hash page # table insert failure for bolted entries. Avoid this by using the secondary hash # group. # # This is different from what kernel does for the non-bolted mapping. With # non-bolted entries kernel will try secondary before removing an existing entry # from hash page table group. With bolted prefer primary hash group and hence # try to insert the page table entry by removing a slot from primary before trying # the secondary hash group. # # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191024093542.29777-3-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 5a43800ff4cb810a1a67e301a496335dd7c06935 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/list.h:9:0, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/btrfs/send.c:7: /kisskb/src/fs/btrfs/send.c: In function 'process_extent': /kisskb/src/include/linux/kernel.h:37:33: warning: 'clone_src_i_size' may be used uninitialized in this function [-Wmaybe-uninitialized] #define IS_ALIGNED(x, a) (((x) & ((typeof(x))(a) - 1)) == 0) ^ /kisskb/src/fs/btrfs/send.c:5088:6: note: 'clone_src_i_size' was declared here u64 clone_src_i_size; ^ WARNING: vmlinux.o(.text+0x31dc): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
