[PATCH v2 2/9] power: supply: axp20x_ac_power: Fix reporting online status

by Samuel Holland

AXP803/AXP813 have a flag that enables/disables the AC power supply input. This flag does not affect the status bits in PWR_INPUT_STATUS. Its effect can be verified by checking the battery charge/discharge state (bit 2 of PWR_INPUT_STATUS), or by examining the current draw on the AC input. Take this flag into account when getting the ONLINE property of the AC input, on PMICs where this flag is present.

[PATCH v2 1/2] virtio-balloon: initialize all vq callbacks

by Daniel Verkamp

Ensure that elements of the callbacks array that correspond to unavailable features are set to NULL; previously, they would be left uninitialized. Since the corresponding names array elements were explicitly set to NULL, the uninitialized callback pointers would not actually be dereferenced; however, the uninitialized callbacks elements would still be read in vp_find_vqs_msix() and used to calculate the number of MSI-X vectors required.

Fix this by skipping any feature processing if the control virtqueue is missing.

[PATCH v3.16] sched/fair: Scale bandwidth quota and period without losing quota/period ratio precision

by Xuewei Zhang

commit 4929a4e6faa0f13289a67cae98139e727f0d4a97 upstream. The quota/period ratio is used to ensure a child task group won't get more bandwidth than the parent task group, and is calculated as: normalized_cfs_quota() = [(quota_us << 20) / period_us] If the quota/period ratio was changed during this scaling due to precision loss, it will cause inconsistency between parent and child task groups. See below example: A userspace container manager (kubelet) does three operations: 1) Create a parent cgroup, set quota to 1,000us and period to 10,000us. 2) Create a few children cgroups. 3) Set quota to 1,000us and period to 10,000us on a child cgroup. These operations are expected to succeed. However, if the scaling of 147/128 happens before step 3, quota and period of the parent cgroup will be changed: new_quota: 1148437ns, 1148us new_period: 11484375ns, 11484us And when step 3 comes in, the ratio of the child cgroup will be 104857, which will be larger than the parent cgroup ratio (104821), and will fail. Scaling them by a factor of 2 will fix the problem.

[patch 16/17] ocfs2: fix the crash due to call ocfs2_get_dlm_debug once less

by akpm＠linux-foundation.org

From: Gang He <GHe(a)suse.com> Subject: ocfs2: fix the crash due to call ocfs2_get_dlm_debug once less Because ocfs2_get_dlm_debug() function is called once less here, ocfs2 file system will trigger the system crash, usually after ocfs2 file system is unmounted. This system crash is caused by a generic memory corruption, these crash backtraces are not always the same, for exapmle, [ 4106.597432] ocfs2: Unmounting device (253,16) on (node 172167785) [ 4116.230719] general protection fault: 0000 [#1] SMP PTI [ 4116.230731] CPU: 3 PID: 14107 Comm: fence_legacy Kdump: [ 4116.230737] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) [ 4116.230772] RIP: 0010:__kmalloc+0xa5/0x2a0 [ 4116.230778] Code: 00 00 4d 8b 07 65 4d 8b [ 4116.230785] RSP: 0018:ffffaa1fc094bbe8 EFLAGS: 00010286 [ 4116.230790] RAX: 0000000000000000 RBX: d310a8800d7a3faf RCX: 0000000000000000 [ 4116.230794] RDX: 0000000000000000 RSI: 0000000000000dc0 RDI: ffff96e68fc036c0 [ 4116.230798] RBP: d310a8800d7a3faf R08: ffff96e6ffdb10a0 R09: 00000000752e7079 [ 4116.230802] R10: 000000000001c513 R11: 0000000004091041 R12: 0000000000000dc0 [ 4116.230806] R13: 0000000000000039 R14: ffff96e68fc036c0 R15: ffff96e68fc036c0 [ 4116.230811] FS: 00007f699dfba540(0000) GS:ffff96e6ffd80000(0000) knlGS:00000 [ 4116.230815] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4116.230819] CR2: 000055f3a9d9b768 CR3: 000000002cd1c000 CR4: 00000000000006e0 [ 4116.230833] Call Trace: [ 4116.230898] ? ext4_htree_store_dirent+0x35/0x100 [ext4] [ 4116.230924] ext4_htree_store_dirent+0x35/0x100 [ext4] [ 4116.230957] htree_dirblock_to_tree+0xea/0x290 [ext4] [ 4116.230989] ext4_htree_fill_tree+0x1c1/0x2d0 [ext4] [ 4116.231027] ext4_readdir+0x67c/0x9d0 [ext4] [ 4116.231040] iterate_dir+0x8d/0x1a0 [ 4116.231056] __x64_sys_getdents+0xab/0x130 [ 4116.231063] ? iterate_dir+0x1a0/0x1a0 [ 4116.231076] ? do_syscall_64+0x60/0x1f0 [ 4116.231080] ? __ia32_sys_getdents+0x130/0x130 [ 4116.231086] do_syscall_64+0x60/0x1f0 [ 4116.231151] entry_SYSCALL_64_after_hwframe+0x49/0xbe [ 4116.231168] RIP: 0033:0x7f699d33a9fb This regression problem was introduced by commit e581595ea29c ("ocfs: no need to check return value of debugfs_create functions").
