alloc_workqueue replaces deprecated create_workqueue(). A dedicated workqueue has been used since the workitem viz (&lio->txq_status_wq.wk.work which maps to octnet_poll_check_txq_status) is involved in a brief poll routine for checking transmit queue status and is an intergral part of normal device operation. WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure, which is a requirement here. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary. flush_workqueue is unnecessary since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty.

Use kmemdup when some other buffer is immediately copied into allocated region. It replaces call to allocation followed by memcpy, by a single call to kmemdup. Signed-off-by: Muhammad Falak R Wani <falakreyaz@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The nf_conntrack_core.c fix in 'net' is not relevant in 'net-next' because we no longer have a per-netns conntrack hash.

2016-04-13net: thunderx: Fix broken of_node_put() code.David Daney1-2/+3
commit b7d3e3d3d21a ("net: thunderx: Don't leak phy device references on -EPROBE_DEFER condition.") incorrectly moved the call to of_node_put() outside of the loop. Under normal loop exit, the node has already had of_node_put() called, so the extra call results in: [ 8.228020] ERROR: Bad of_node_put() on /soc@0/pci@848000000000/mrml-bridge0@1,0/bgx0/xlaui00 [ 8.239433] CPU: 16 PID: 608 Comm: systemd-udevd Not tainted 4.6.0-rc1-numa+ #157 [ 8.247380] Hardware name: www.cavium.com EBB8800/EBB8800, BIOS 0.3 Mar 2 2016 [ 8.273541] Call trace: [ 8.273550] [<fffffc0008097364>] dump_backtrace+0x0/0x210 [ 8.273557] [<fffffc0008097598>] show_stack+0x24/0x2c [ 8.273560] [<fffffc0008399ed0>] dump_stack+0x8c/0xb4 [ 8.273566] [<fffffc00085aa828>] of_node_release+0xa8/0xac [ 8.273570] [<fffffc000839cad8>] kobject_cleanup+0x8c/0x194 [ 8.273573] [<fffffc000839c97c>] kobject_put+0x44/0x6c [ 8.273576] [<fffffc00085a9ab0>] of_node_put+0x24/0x30 [ 8.273587] [<fffffc0000bd0f74>] bgx_probe+0x17c/0xcd8 [thunder_bgx] [ 8.273591] [<fffffc00083ed220>] pci_device_probe+0xa0/0x114 [ 8.273596] [<fffffc0008473fbc>] driver_probe_device+0x178/0x418 [ 8.273599] [<fffffc000847435c>] __driver_attach+0x100/0x118 [ 8.273602] [<fffffc0008471b58>] bus_for_each_dev+0x6c/0xac [ 8.273605] [<fffffc0008473884>] driver_attach+0x30/0x38 [ 8.273608] [<fffffc00084732f4>] bus_add_driver+0x1f8/0x29c [ 8.273611] [<fffffc0008475028>] driver_register+0x70/0x110 [ 8.273617] [<fffffc00083ebf08>] __pci_register_driver+0x60/0x6c [ 8.273623] [<fffffc0000bf0040>] bgx_init_module+0x40/0x48 [thunder_bgx] [ 8.273626] [<fffffc0008090d04>] do_one_initcall+0xcc/0x1c0 [ 8.273631] [<fffffc0008198abc>] do_init_module+0x68/0x1c8 [ 8.273635] [<fffffc0008125668>] load_module+0xf44/0x11f4 [ 8.273638] [<fffffc0008125b64>] SyS_finit_module+0xb8/0xe0 [ 8.273641] [<fffffc0008093b30>] el0_svc_naked+0x24/0x28 Go back to the previous (correct) code that only did the extra of_node_put() call on early exit from the loop.
