-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.

-
-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
-
