345 Besides management of swap is one of complicated parts of memcg,
346 call path of swap-in at swapoff is not same as usual swap-in path..
347 It's worth to be tested explicitly.
348
349 For example, test like following is good.
350 (Shell-A)
351 # mount -t cgroup none /cgroup -t memory
352 # mkdir /cgroup/test
353 # echo 40M > /cgroup/test/memory.limit_in_bytes
354 # echo 0 > /cgroup/test/tasks
355 Run malloc(100M) program under this. You'll see 60M of swaps.

357 # move all tasks in /cgroup/test to /cgroup

359 # rmdir /test/cgroup
360 # kill malloc task.

362 Of course, tmpfs v.s. swapoff test should be tested, too.

2028oom-killing altogether for this process. 2028oom-killing altogether for this process.
2029 2029
2030The process to be killed in an out-of-memory situation is selected among all others
2031based on its badness score. This value equals the original memory size of the process
2032and is then updated according to its CPU time (utime + stime) and the
2033run time (uptime - start time). The longer it runs the smaller is the score.
2034Badness score is divided by the square root of the CPU time and then by
2035the double square root of the run time.
2036
2037Swapped out tasks are killed first. Half of each child's memory size is added to
2038the parent's score if they do not share the same memory. Thus forking servers
2039are the prime candidates to be killed. Having only one 'hungry' child will make
2040parent less preferable than the child.
2041
2042/proc/<pid>/oom_score shows process' current badness score.
2043
2044The following heuristics are then applied:
2045 * if the task was reniced, its score doubles
2046 * superuser or direct hardware access tasks (CAP_SYS_ADMIN, CAP_SYS_RESOURCE
2047 or CAP_SYS_RAWIO) have their score divided by 4
2048 * if oom condition happened in one cpuset and checked task does not belong
2049 to it, its score is divided by 8
2050 * the resulting score is multiplied by two to the power of oom_adj, i.e.
2051 points <<= oom_adj when it is positive and
2052 points >>= -(oom_adj) otherwise
2053
2054The task with the highest badness score is then selected and its children
2055are killed, process itself will be killed in an OOM situation when it does
2056not have children or some of them disabled oom like described above.

91 * Atomic logical eraseblock change
92 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
93 *
94 * Atomic logical eraseblock change operation is called using the %UBI_IOCEBCH
95 * ioctl command of the corresponding UBI volume character device. A pointer to
96 * a &struct ubi_leb_change_req object has to be passed to the ioctl. Then the

98 * should be done in case of the "volume update" ioctl).
99 *
100 * Logical eraseblock map
101 * ~~~~~~~~~~~~~~~~~~~~~
102 *
103 * To map a logical eraseblock to a physical eraseblock, the %UBI_IOCEBMAP
104 * ioctl command should be used. A pointer to a &struct ubi_map_req object is
105 * expected to be passed. The ioctl maps the requested logical eraseblock to
106 * a physical eraseblock and returns. Only non-mapped logical eraseblocks can
107 * be mapped. If the logical eraseblock specified in the request is already
108 * mapped to a physical eraseblock, the ioctl fails and returns error.
109 *
110 * Logical eraseblock unmap
111 * ~~~~~~~~~~~~~~~~~~~~~~~~
112 *
113 * To unmap a logical eraseblock to a physical eraseblock, the %UBI_IOCEBUNMAP
114 * ioctl command should be used. The ioctl unmaps the logical eraseblocks,
115 * schedules corresponding physical eraseblock for erasure, and returns. Unlike
116 * the "LEB erase" command, it does not wait for the physical eraseblock being
117 * erased. Note, the side effect of this is that if an unclean reboot happens
118 * after the unmap ioctl returns, you may find the LEB mapped again to the same
119 * physical eraseblock after the UBI is run again.
120 *
121 * Check if logical eraseblock is mapped
122 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
123 *
124 * To check if a logical eraseblock is mapped to a physical eraseblock, the
125 * %UBI_IOCEBISMAP ioctl command should be used. It returns %0 if the LEB is
126 * not mapped, and %1 if it is mapped.
127 *
128 * Set an UBI volume property
129 * ~~~~~~~~~~~~~~~~~~~~~~~~~
130 *
131 * To set an UBI volume property the %UBI_IOCSETPROP ioctl command should be
132 * used. A pointer to a &struct ubi_set_prop_req object is expected to be
133 * passed. The object describes which property should be set, and to which value
134 * it should be set.
