2016-07-23mm: memcontrol: fix cgroup creation failure after many small jobsJohannes Weiner3-24/+87
The memory controller has quite a bit of state that usually outlives the cgroup and pins its CSS until said state disappears. At the same time it imposes a 16-bit limit on the CSS ID space to economically store IDs in the wild. Consequently, when we use cgroups to contain frequent but small and short-lived jobs that leave behind some page cache, we quickly run into the 64k limitations of outstanding CSSs. Creating a new cgroup fails with -ENOSPC while there are only a few, or even no user-visible cgroups in existence. Although pinning CSSs past cgroup removal is common, there are only two instances that actually need an ID after a cgroup is deleted: cache shadow entries and swapout records. Cache shadow entries reference the ID weakly and can deal with the CSS having disappeared when it's looked up later. They pose no hurdle. Swap-out records do need to pin the css to hierarchically attribute swapins after the cgroup has been deleted; though the only pages that remain swapped out after offlining are tmpfs/shmem pages. And those references are under the user's control, so they are manageable. This patch introduces a private 16-bit memcg ID and switches swap and cache shadow entries over to using that. This ID can then be recycled after offlining when the CSS remains pinned only by objects that don't specifically need it. This script demonstrates the problem by faulting one cache page in a new cgroup and deleting it again: set -e mkdir -p pages for x in `seq 128000`; do [ $((x % 1000)) -eq 0 ] && echo $x mkdir /cgroup/foo echo $$ >/cgroup/foo/cgroup.procs echo trex >pages/$x echo $$ >/cgroup/cgroup.procs rmdir /cgroup/foo done When run on an unpatched kernel, we eventually run out of possible IDs even though there are no visible cgroups: [root@ham ~]# ./cssidstress.sh [...] 65000 mkdir: cannot create directory '/cgroup/foo': No space left on device After this patch, the IDs get released upon cgroup destruction and the cache and css objects get released once memory reclaim kicks in.

2016-07-22gpio: tegra: don't auto-enable for COMPILE_TESTArnd Bergmann1-2/+5
I stumbled over a build error with COMPILE_TEST and CONFIG_OF disabled: drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe': drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node' The problem is that the newly added GPIO_TEGRA Kconfig symbol does not have a dependency on CONFIG_OF. However, there is another problem here as the driver gets enabled unconditionally whenever COMPILE_TEST is set. This fixes both problems, by making the symbol user-visible when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y. As a side-effect, it is now possible to compile-test a Tegra kernel with GPIO support disabled, which is harmless.

2016-07-22libceph: apply new_state before new_up_client on incrementalsIlya Dryomov1-43/+113
Currently, osd_weight and osd_state fields are updated in the encoding order. This is wrong, because an incremental map may look like e.g. new_up_client: { osd=6, addr=... } # set osd_state and addr new_state: { osd=6, xorstate=EXISTS } # clear osd_state Suppose osd6's current osd_state is EXISTS (i.e. osd6 is down). After applying new_up_client, osd_state is changed to EXISTS | UP. Carrying on with the new_state update, we flip EXISTS and leave osd6 in a weird "!EXISTS but UP" state. A non-existent OSD is considered down by the mapping code 2087 for (i = 0; i < pg->pg_temp.len; i++) { 2088 if (ceph_osd_is_down(osdmap, pg->pg_temp.osds[i])) { 2089 if (ceph_can_shift_osds(pi)) 2090 continue; 2091 2092 temp->osds[temp->size++] = CRUSH_ITEM_NONE; and so requests get directed to the second OSD in the set instead of the first, resulting in OSD-side errors like: [WRN] : client.4239 192.168.122.21:0/2444980242 misdirected client.4239.1:2827 pg 2.5df899f2 to osd.4 not [1,4,6] in e680/680 and hung rbds on the client: [ 493.566367] rbd: rbd0: write 400000 at 11cc00000 (0) [ 493.566805] rbd: rbd0: result -6 xferred 400000 [ 493.567011] blk_update_request: I/O error, dev rbd0, sector 9330688 The fix is to decouple application from the decoding and: - apply new_weight first - apply new_state before new_up_client - twiddle osd_state flags if marking in - clear out some of the state if osd is destroyed Fixes: http://tracker.ceph.com/issues/14901 Cc: stable@vger.kernel.org # 3.15+: 6dd74e44dc1d: libceph: set 'exists' flag for newly up osd Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Josh Durgin <jdurgin@redhat.com>

2016-07-19packet: fix second argument of sock_tx_timestamp()Yoshihiro Shimoda1-3/+3
This patch fixes an issue that a syscall (e.g. sendto syscall) cannot work correctly. Since the sendto syscall doesn't have msg_control buffer, the sock_tx_timestamp() in packet_snd() cannot work correctly because the socks.tsflags is set to 0. So, this patch sets the socks.tsflags to sk->sk_tsflags as default. Fixes: c14ac9451c34 ("sock: enable timestamping using control messages") Reported-by: Kazuya Mizuguchi <kazuya.mizuguchi.ks@renesas.com> Reported-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Acked-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

2016-07-19Input: synaptics-rmi4 - fix maximum size check for F12 control register 8Andrew Duggan1-4/+5
According to the RMI4 spec the maximum size of F12 control register 8 is 15 bytes. The current code incorrectly reports an error if control 8 is greater then 14. Making sensors with a control register 8 with 15 bytes unusable.

2016-07-19net: switchdev: change ageing_time type to clock_tVivien Didelot1-1/+1
The switchdev value for the SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME attribute is a clock_t and requires to use helpers such as clock_t_to_jiffies() to convert to milliseconds. Change ageing_time type from u32 to clock_t to make it explicit.

2016-07-19Update maintainer for EHEA driver.Douglas Miller1-1/+1
Since Thadeu left IBM, EHEA has gone mostly unmaintained, since his email address doesn't work anymore. I'm stepping up to help maintain this driver upstream. I'm adding Thadeu's personal e-mail address in Cc, hoping that we can get his ack.
