lookup next chunk in radix-tree leaf node\n* iterating through slots in this chunk\n\nMain iterator function radix_tree_next_chunk() returns pointer to first\nslot, and stores in the struct radix_tree_iter index of next-to-last slot.\n For tagged-iterating it also constuct bitmask of tags for retunted chunk.\n All additional logic implemented as static-inline functions and macroses.\n\nAlso adds radix_tree_find_next_bit() static-inline variant of\nfind_next_bit() optimized for small constant size arrays, because\nfind_next_bit() too heavy for searching in an array with one/two long\nelements.\n\n[akpm@linux-foundation.org: rework comments a bit]\nSigned-off-by: Konstantin Khlebnikov \u003ckhlebnikov@openvz.org\u003e\nTested-by: Hugh Dickins

When the pid namespace is used in conjunction with the other\nnamespaces in order to create a linux container, the reboot syscall leads\nto some problems.\n\nA container can reboot the host. That can be fixed by dropping the\nsys_reboot capability but we are unable to correctly to poweroff/\nhalt/reboot a container and the container stays stuck at the shutdown time\nwith the container\u0027s init process waiting indefinitively.\n\nAfter several attempts, no solution from userspace was found to reliabily\nhandle the shutdown from a container.\n\nThis patch propose to make the init process of the child pid namespace to\nexit with a signal status set to : SIGINT if the child pid namespace\ncalled \"halt/poweroff\" and SIGHUP if the child pid namespace called\n\"reboot\". When the reboot syscall is called and we are not in the initial\npid namespace, we kill the pid namespace for \"HALT\", \"POWEROFF\",\n\"RESTART\", and \"RESTART2\". Otherwise we return EINVAL.\n\nReturning EINVAL is also an easy way to check if this feature is supported\nby the kernel when invoking another \u0027reboot\u0027 option like CAD.\n\nBy this way the parent process of the child pid namespace knows if it\nrebooted or not and can take the right decision.\n\nTest case:\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\n#include \u003calloca.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003csched.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003csignal.h\u003e\n#include \u003csys/reboot.h\u003e\n#include \u003csys/types.h\u003e\n#include \u003csys/wait.h\u003e\n\n#include \u003clinux/reboot.h\u003e\n\nstatic int do_reboot(void *arg)\n{\n int *cmd \u003d arg;\n\n if (reboot(*cmd))\n printf(\"failed to reboot(%d): %m\\n\", *cmd);\n}\n\nint test_reboot(int cmd, int sig)\n{\n long stack_size \u003d 4096;\n void *stack \u003d alloca(stack_size) + stack_size;\n int status;\n pid_t ret;\n\n ret \u003d clone(do_reboot, stack, CLONE_NEWPID | SIGCHLD, \u0026cmd);\n if (ret \u003c 0) {\n printf(\"failed to clone: %m\\n\");\n return -1;\n }\n\n if (wait(\u0026status) \u003c 0) {\n printf(\"unexpected wait error: %m\\n\");\n return -1;\n }\n\n if (!WIFSIGNALED(status)) {\n printf(\"child process exited but was not signaled\\n\");\n return -1;\n }\n\n if (WTERMSIG(status) !\u003d sig) {\n printf(\"signal termination is not the one expected\\n\");\n return -1;\n }\n\n return 0;\n}\n\nint main(int argc, char *argv[])\n{\n int status;\n\n status \u003d test_reboot(LINUX_REBOOT_CMD_RESTART, SIGHUP);\n if (status \u003c 0)\n return 1;\n printf(\"reboot(LINUX_REBOOT_CMD_RESTART) succeed\\n\");\n\n status \u003d test_reboot(LINUX_REBOOT_CMD_RESTART2, SIGHUP);\n if (status \u003c 0)\n return 1;\n printf(\"reboot(LINUX_REBOOT_CMD_RESTART2) succeed\\n\");\n\n status \u003d test_reboot(LINUX_REBOOT_CMD_HALT, SIGINT);\n if (status \u003c 0)\n return 1;\n printf(\"reboot(LINUX_REBOOT_CMD_HALT) succeed\\n\");\n\n status \u003d test_reboot(LINUX_REBOOT_CMD_POWER_OFF, SIGINT);\n if (status \u003c 0)\n return 1;\n printf(\"reboot(LINUX_REBOOT_CMD_POWERR_OFF) succeed\\n\");\n\n status \u003d test_reboot(LINUX_REBOOT_CMD_CAD_ON, -1);\n if (status \u003e\u003d 0) {\n printf(\"reboot(LINUX_REBOOT_CMD_CAD_ON) should have failed\\n\");\n return 1;\n }\n printf(\"reboot(LINUX_REBOOT_CMD_CAD_ON) has failed as expected\\n\");\n\n return 0;\n}\n\n[akpm@linux-foundation.org: tweak and add comments]\n[akpm@linux-foundation.org: checkpatch fixes]\nSigned-off-by: Daniel Lezcano \u003cdaniel.lezcano@free.fr\u003e\nAcked-by: Serge Hallyn \u003cserge.hallyn@canonical.com\u003e\nTested-by: Serge Hallyn \u003cserge.hallyn@canonical.com\u003e\nReviewed-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@gmail.com\u003e\nCc: \"Eric W.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.
