2016-01-07spi: sun4i: Prevent chip-select from being activated twice before a transferMarcus Weseloh
The SPI core calls set_cs before a transfer, but the SUN4I_CTL_CS_MANUAL flag is only set in transfer_one. This leads to the following pattern on the chip-select line (with runtime power-management on every transfer, without it only on the first one): activate, deactivate, activate, transfer, deactivate Moving the configuration of the SUN4I_CTL_CS_MANUAL flag from transfer_one to set_cs removes the double activation.

2016-01-07regulator: core: remove some dead codeDan Carpenter
Originally queue_delayed_work() used to negative error codes or 0 and 1 on success depending if the work was queued or not. It caused a lot of bugs where people treated all non-zero returns as failures so we changed it to return bool instead in d4283e937861 ('workqueue: make queueing functions return bool'). Now it never returns failure. Checking for negative values causes a static checker warning since it is impossible based on the bool type.

Chuck says: "In that case, nfsd would pass down an xdr_buf that has one byte in a page, one byte in another page, and a two-byte XDR pad.

2016-01-07ARM: Fix broken USB support in multi_v7_defconfig for sunxi devicesTimo Sigurdsson
Commit 69fb4dcada77 ("power: Add an axp20x-usb-power driver") introduced a new driver for the USB power supply used on various Allwinner based SBCs. However, the driver was not added to multi_v7_defconfig which breaks USB support for some boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power supply during boot by default if the driver isn't present. (This was not the case in linux 4.3 or lower where the USB power was always left on.) Hence, add the driver to multi_v7_defconfig in order to keep USB support working on those boards that require it.

2016-01-07perf tests: No need to set attr.sample_freq in the perf time to TSC testArnaldo Carvalho de Melo
We were asking for a 4kHz sample_freq, making the test fail needlessly when the system reduced /proc/sys/kernel/perf_event_max_sample_rate below that. In this test we only look at the PERF_SAMPLE_TIME fields in PERF_RECORD_ meta events, no need to set sample_freq. Thanks to Namhyung for suggesting that max_sample_rate could be the reason for the test failure, seeing the 'perf test -vv' output I sent.

2016-01-07btrfs: statfs: report zero available if metadata are exhaustedDavid Sterba
There is one ENOSPC case that's very confusing. There's Available greater than zero but no file operation succeds (besides removing files). This happens when the metadata are exhausted and there's no possibility to allocate another chunk. In this scenario it's normal that there's still some space in the data chunk and the calculation in df reflects that in the Avail value. To at least give some clue about the ENOSPC situation, let statfs report zero value in Avail, even if there's still data space available. Current: /dev/sdb1 4.0G 3.3G 719M 83% /mnt/test New: /dev/sdb1 4.0G 3.3G 0 100% /mnt/test We calculate the remaining metadata space minus global reserve. If this is (supposedly) smaller than zero, there's no space. But this does not hold in practice, the exhausted state happens where's still some positive delta. So we apply some guesswork and compare the delta to a 4M threshold. (Practically observed delta was 2M.) We probably cannot calculate the exact threshold value because this depends on the internal reservations requested by various operations, so some operations that consume a few metadata will succeed even if the Avail is zero. But this is better than the other way around. Signed-off-by: David Sterba <dsterba@suse.com>

2016-01-07btrfs: allocate root item at snapshot ioctl timeDavid Sterba
The actual snapshot creation is delayed until transaction commit. If we cannot get enough memory for the root item there, we have to fail the whole transaction commit which is bad.

2016-01-07btrfs: use smaller type for btrfs_path locksDavid Sterba
The values of btrfs_path::locks are 0 to 4, fit into a u8. Let's see: * overall size of btrfs_path drops down from 136 to 112 (-24 bytes), * better packing in a slab page +6 objects * the whole structure now fits to 2 cachelines * slight decrease in code size: text data bss dec hex filename 938731 43670 23144 1005545 f57e9 fs/btrfs/btrfs.ko.before 938203 43670 23144 1005017 f55d9 fs/btrfs/btrfs.ko.after (and the generated assembly does not change much) The main purpose is to decrease the size of the structure without affecting performance. The byte access is usually well behaving accross arches, the locks are not accessed frequently and sometimes just compared to zero. Note for further size reduction attempts: the slots could be made u16 but this might generate worse code on some arches (non-byte and non-int access). Also the range of operations on slots is wider compared to locks and the potential performance drop should be evaluated first. Signed-off-by: David Sterba <dsterba@suse.com>

2016-01-07Btrfs: use linux/sizes.h to represent constantsByongho Lee
We use many constants to represent size and offset value. And to make code readable we use '256 * 1024 * 1024' instead of '268435456' to represent '256MB'. However we can make far more readable with 'SZ_256MB' which is defined in the 'linux/sizes.h'. So this patch replaces 'xxx * 1024 * 1024' kind of expression with single 'SZ_xxxMB' if 'xxx' is a power of 2 then 'xxx * SZ_1M' if 'xxx' is not a power of 2.

2016-01-07btrfs: don't use slab cache for struct btrfs_delalloc_workDavid Sterba
Although we prefer to use separate caches for various structs, it seems better not to do that for struct btrfs_delalloc_work. Objects of this type are allocated rarely, when transaction commit calls btrfs_start_delalloc_roots, requesting delayed iputs. The objects are temporary (with some IO involved) but still allocated and freed within __start_delalloc_inodes. Memory allocation failure is handled. The slab cache is empty most of the time (observed on several systems), so if we need to allocate a new slab object, the first one has to allocate a full page. In a potential case of low memory conditions this might fail with higher probability compared to using the generic slab caches. Signed-off-by: David Sterba <dsterba@suse.com>
