But, # the dump_page() itself accesses struct page to determine how to print # it, and therefore gets into a recursive loop. # # For example: # # dump_page() # __dump_page() # PageSlab(page) # PF_POISONED_CHECK(page) # VM_BUG_ON_PGFLAGS(PagePoisoned(page), page) # dump_page() recursion loop. # # Link: http://lkml.kernel.org/r/20180702180536.2552-1-pasha.tatashin@oracle.com # Fixes: f165b378bbdf ("mm: uninitialized struct page poisoning sanity checking") # Signed-off-by: Pavel Tatashin <pasha.tatashin@oracle.com> # Acked-by: Michal Hocko <mhocko@suse.com> # Cc: <stable@vger.kernel.org> # Signed-off-by: Andrew Morton <akpm@linux-foundation.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < git log --format=%s --max-count=1 fc36def997cfd6cbff3eda4f82853a5c311c5466 # < make -s -j 48 ARCH=arm O=/kisskb/build/linus_imx_v6_v7_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- imx_v6_v7_defconfig # make -s -j 48 ARCH=arm O=/kisskb/build/linus_imx_v6_v7_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1256:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2497:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1819:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:146:32: warning: 'levelspread[<U76e0>]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:94:6: note: 'levelspread[<U76e0>]' was declared here /kisskb/src/sound/soc/codecs/wm8960.c: In function 'wm8960_configure_clocking': /kisskb/src/sound/soc/codecs/wm8960.c:803:70: warning: 'j' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/codecs/wm8960.c:800:68: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/fsl/fsl_ssi.c: In function 'fsl_ssi_hw_params': /kisskb/src/sound/soc/fsl/fsl_ssi.c:769:7: warning: 'baudrate' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/fsl/fsl_ssi.c:680:25: note: 'baudrate' was declared here /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/dma-buf/reservation.c: In function 'reservation_object_add_shared_fence': /kisskb/src/drivers/dma-buf/reservation.c:225:6: warning: 'k' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1353:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1310:6: note: 'pwr_level_cisco' was declared here Completed OK # rm -rf /kisskb/build/linus_imx_v6_v7_defconfig_arm # Build took: 0:01:36.445469
