[PATCH 4.14 0/5] perf machine: Workaround missing maps for x86 PTI entry trampolines

by Adrian Hunter

Hi x86 PTI trampolines were backported to 4.14, refer commit: c631a16e5b84521ae80ab10d47cd6ccd2afc6817 ("x86/entry/64: Create a per-CPU SYSCALL entry trampoline") so the corresponding perf tools workaround also needs to be backported. Here are 5 patches for 4.14 stable backported from 4.18, to address that. Regards Adrian

[PATCH 1/2] btrfs: Enhance btrfs_trim_fs function to handle error better

by Qu Wenruo

Commit 93bba24d4b5ad1e5cd8b43f64e66ff9d6355dd20 upstream. Function btrfs_trim_fs() doesn't handle errors in a consistent way. If error happens when trimming existing block groups, it will skip the remaining blocks and continue to trim unallocated space for each device. The return value will only reflect the final error from device trimming. This patch will fix such behavior by: 1) Recording the last error from block group or device trimming The return value will also reflect the last error during trimming. Make developer more aware of the problem. 2) Continuing trimming if possible If we failed to trim one block group or device, we could still try the next block group or device. 3) Report number of failures during block group and device trimming It would be less noisy, but still gives user a brief summary of what's going wrong. Such behavior can avoid confusion for cases like failure to trim the first block group and then only unallocated space is trimmed.

[PATCH] gfs2: Put bitmap buffers in put_super

by Andreas Gruenbacher

commit 10283ea525d30f2e99828978fd04d8427876a7ad upstream. gfs2_put_super calls gfs2_clear_rgrpd to destroy the gfs2_rgrpd objects attached to the resource group glocks. That function should release the buffers attached to the gfs2_bitmap objects (bi_bh), but the call to gfs2_rgrp_brelse for doing that is missing. When gfs2_releasepage later runs across these buffers which are still referenced, it refuses to free them. This causes the pages the buffers are attached to to remain referenced as well. With enough mount/unmount cycles, the system will eventually run out of memory. Fix this by adding the missing call to gfs2_rgrp_brelse in gfs2_clear_rgrpd. (Also fix a gfs2_rgrp_relse -> gfs2_rgrp_brelse typo in a comment.)

[PATCH] zram: close udev startup race condition as default groups

by Minchan Kim

commit fef912bf860e upstream. commit 98af4d4df889 upstream. I got a report from Howard Chen that he saw zram and sysfs race(ie, zram block device file is created but sysfs for it isn't yet) when he tried to create new zram devices via hotadd knob. v4.20 kernel fixes it by [1, 2] but it's too large size to merge into -stable so this patch fixes the problem by registering defualt group by Greg KH's approach[3].

[PATCH] ALSA: hda/realtek - fix headset mic detection for MSI MS-B171

by Anisse Astier

MSI Cubi N 8GL (MS-B171) needs the same fixup as its older model, the MS-B120, in order for the headset mic to be properly detected. They both use a single 3-way jack for both mic and headset with an ALC283 codec, with the same pins used.

[git:media_tree/master] media: dvb-pll: fix tuner frequency ranges

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: dvb-pll: fix tuner frequency ranges Author: Mauro Carvalho Chehab <mchehab+samsung(a)kernel.org> Date: Tue Nov 20 05:19:36 2018 -0500 Tuners should report frequencies in Hz. That works fine on most drivers, but, in the case of dvb-pll, some settings are for satellite tuners, while others are for terrestrial/cable ones. The code was trying to solve it at probing time, but that doesn't work, as, when _attach is called, the delivery system may be wrong. Fix it by ensuring that all frequencies are in Hz at the per-tuner max/min values. While here, add a debug message, as this would help to debug any issues there. It partially fixes the following bug: https://bugzilla.opensuse.org/show_bug.cgi?id=1116374 Fixes: a3f90c75b833 ("media: dvb: convert tuner_info frequencies to Hz") Reported-by: Stakanov Schufter <stakanov(a)eclipso.eu> Reported-by: Takashi Iwai <tiwai(a)suse.de> Cc: stable(a)vger.kernel.org # For 4.19 Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung(a)kernel.org> drivers/media/dvb-frontends/dvb-pll.c | 103 ++++++++++++++++------------------ 1 file changed, 48 insertions(+), 55 deletions(-) --- diff --git a/drivers/media/dvb-frontends/dvb-pll.c b/drivers/media/dvb-frontends/dvb-pll.c index 6d4b2eec67b4..fff5816f6ec4 100644 --- a/drivers/media/dvb-frontends/dvb-pll.c +++ b/drivers/media/dvb-frontends/dvb-pll.c @@ -80,8 +80,8 @@ struct dvb_pll_desc { static const struct dvb_pll_desc dvb_pll_thomson_dtt7579 = { .name = "Thomson dtt7579", -
