Subject: [PATCH] Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on
|
|
||||||
Apple
|
|
||||||
|
|
||||||
Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
|
|
||||||
and also added btbcm_read_verbose_config() to read extra information
|
|
||||||
about the hardware. It's returning errors on some macbooks:
|
|
||||||
|
|
||||||
Bluetooth: hci0: BCM: Read verbose config info failed (-16)
|
|
||||||
|
|
||||||
Which makes us error out of the setup function. Since this
|
|
||||||
probe isn't critical to operate the chip, this patch just changes
|
|
||||||
things to carry on when it fails.

Subject: [PATCH 1/2] block: loop: convert to per-device workqueue
|
|
||||||
|
|
||||||
Documentation/workqueue.txt:
|
|
||||||
If there is dependency among multiple work items used
|
|
||||||
during memory reclaim, they should be queued to separate
|
|
||||||
wq each with WQ_MEM_RECLAIM.
|
|
||||||
|
|
||||||
Loop devices can be stacked, so we have to convert to per-device
|
|
||||||
workqueue. One example is Fedora live CD.

Subject: [PATCH 2/2] block: loop: avoiding too many pending per work I/O
|
|
||||||
|
|
||||||
If there are too many pending per work I/O, too many
|
|
||||||
high priority work thread can be generated so that
|
|
||||||
system performance can be effected.
|
|
||||||
|
|
||||||
This patch limits the max_active parameter of workqueue as 16.
|
|
||||||
|
|
||||||
This patch fixes Fedora 22 live booting performance
|
|
||||||
regression when it is booted from squashfs over dm
|
|
||||||
based on loop, and looks the following reasons are
|
|
||||||
related with the problem:
|
|
||||||
|
|
||||||
- not like other filesyststems(such as ext4), squashfs
|
|
||||||
is a bit special, and I observed that increasing I/O jobs
|
|
||||||
to access file in squashfs only improve I/O performance a
|
|
||||||
little, but it can make big difference for ext4
|
|
||||||
|
|
||||||
- nested loop: both squashfs.img and ext3fs.img are mounted
|
|
||||||
as loop block, and ext3fs.img is inside the squashfs
|
|
||||||
|
|
||||||
- during booting, lots of tasks may run concurrently

Subject: [PATCH] Enable loading of bitmaps for dm-md-raid1.
|
|
||||||
|
|
||||||
This is also a temporary hack to systems with junk in the rest
|
|
||||||
of the bitmap super (instead of zeroes) to boot. This is done by
|
|
||||||
checking mddev->sync_super (which is exclusively set by dm-raid)
|
|
||||||
is null.
|
|
||||||
|
|
||||||
These changes also include zeroing of most bitmap pages while
|
|
||||||
allocating so we are sure that the junk is not coming from memory.
