[PATCH 3.18.y 5/5] switch ->setxattr() to passing dentry and inode separately

by Seung-Woo Kim

From: Al Viro <viro(a)zeniv.linux.org.uk> smack ->d_instantiate() uses ->setxattr(), so to be able to call it before we'd hashed the new dentry and attached it to inode, we need ->setxattr() instances getting the inode as an explicit argument rather than obtaining it from dentry. Similar change for ->getxattr() had been done in commit ce23e64. Unlike ->getxattr() (which is used by both selinux and smack instances of ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately it got missed back then.

patch "USB: add quirk for WORLDE Controller KS49 or Prodipe MIDI 49C USB" added to usb-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: add quirk for WORLDE Controller KS49 or Prodipe MIDI 49C USB to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 3ae259faaf19e9b6284fe786e3bd4626df143cd7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Maxence=20Dupr=C3=A8s?= <xpros64(a)hotmail.fr> Date: Wed, 8 Aug 2018 23:56:33 +0000 Subject: USB: add quirk for WORLDE Controller KS49 or Prodipe MIDI 49C USB controller WORLDE Controller KS49 or Prodipe MIDI 49C USB controller cause a -EPROTO error, a communication restart and loop again. This issue has already been fixed for KS25. https://lore.kernel.org/patchwork/patch/753077/ I just add device 201 for KS49 in quirks.c to get it works.

perf: Support uncore in 4.9.112

by Jin, Yao

Hi, The stable kernel 4.9.112 has supported Intel uncore feature in perf core. While it also needs the perf tool supporting to let perf uncore feature work. Following backport patches enables basic perf uncore feature in 4.9.112. For example, on skylake desktop, root@skl:~# uname -a Linux skl 4.9.112+ #2 SMP Mon Jul 16 17:35:25 CST 2018 x86_64 x86_64 x86_64 GNU/Linux root@skl:~# perf list | grep unc_ unc_arb_coh_trk_requests.all unc_arb_trk_occupancy.all unc_arb_trk_occupancy.cycles_with_any_request unc_arb_trk_requests.all unc_arb_trk_requests.drd_direct unc_arb_trk_requests.writes unc_cbo_cache_lookup.any_es unc_cbo_cache_lookup.any_i unc_cbo_cache_lookup.any_m unc_cbo_cache_lookup.any_mesi unc_cbo_cache_lookup.read_es unc_cbo_cache_lookup.read_i unc_cbo_cache_lookup.read_mesi unc_cbo_cache_lookup.write_es unc_cbo_cache_lookup.write_m unc_cbo_cache_lookup.write_mesi unc_cbo_xsnp_response.hit_xcore unc_cbo_xsnp_response.hitm_xcore unc_cbo_xsnp_response.miss_eviction unc_cbo_xsnp_response.miss_xcore root@skl:~# perf stat -a -e unc_cbo_cache_lookup.any_es sleep 1 Performance counter stats for 'system wide': 147,229 unc_cbo_cache_lookup.any_es 1.001204726 seconds time elapsed These patches are divided into 2 parts, perf core part and perf tool part.

[PATCH 08/10] bcache: set max writeback rate when I/O request is idle

by Coly Li

Commit b1092c9af9ed ("bcache: allow quick writeback when backing idle") allows the writeback rate to be faster if there is no I/O request on a bcache device. It works well if there is only one bcache device attached to the cache set. If there are many bcache devices attached to a cache set, it may introduce performance regression because multiple faster writeback threads of the idle bcache devices will compete the btree level locks with the bcache device who have I/O requests coming. This patch fixes the above issue by only permitting fast writebac when all bcache devices attached on the cache set are idle. And if one of the bcache devices has new I/O request coming, minimized all writeback throughput immediately and let PI controller __update_writeback_rate() to decide the upcoming writeback rate for each bcache device. Also when all bcache devices are idle, limited wrieback rate to a small number is wast of thoughput, especially when backing devices are slower non-rotation devices (e.g. SATA SSD). This patch sets a max writeback rate for each backing device if the whole cache set is idle. A faster writeback rate in idle time means new I/Os may have more available space for dirty data, and people may observe a better write performance then. Please note bcache may change its cache mode in run time, and this patch still works if the cache mode is switched from writeback mode and there is still dirty data on cache.
