2016-01-08locks: prink more detail when there are leaked locksJeff Layton
Right now, we just get WARN_ON_ONCE, which is not particularly helpful. Have it dump some info about the locks and the inode to make it easier to track down leaked locks in the future. Signed-off-by: Jeff Layton <jeff.layton@primarydata.com> Acked-by: "J. Bruce Fields" <bfields@fieldses.org>

2016-01-08Revert "block: Split bios on chunk boundaries"Jens Axboe
This reverts commit d3805611130af9b911e908af9f67a3f64f4f0914. If we end up splitting on the first segment, we don't adjust the sector count. That results in hitting a BUG() with attempting to split 0 sectors. As this is just a performance issue and not a regression since 4.3 release, let's just rever this change. That gives us more time to test a real fix for 4.5, which would be marked for stable anyway.

2016-01-08perf report: Change default to use event group viewNamhyung Kim
The event group view feature is to see related events together. To use the group view, events should be recorded as a group with a dedicated syntax of surrounding events by braces (-e '{ evt1, evt2, ... }'). Also 'perf report' also requires the --group option to enable it. However it's almost always beneficial to use the group view to see the group events as it's more expressive. And I think it's more natural to see events together if they are recorded as a group. Thus this patch changes the default value to enable it. If users don't want to see like it and keep the original behavior, they can set the report.group config variable to false and/or use --no-group option in the 'perf report' command line.

sleeps (<20 ms) Since msleep() may sleep longer than intended time for values less than 20ms, this patch allows the use of usleep_range for waits less that 20ms. usleep_range is a finer precision implementation of msleep and is designed to be a drop-in replacement for udelay where a precise sleep/busy-wait is unnecessary.

2016-01-08i40e: Fix Rx hash reported to the stack by our driverAnjali Singhai Jain
If the driver calls skb_set_hash even with a zero hash, that indicates to the stack that the hash calculation is offloaded in hardware. So the Stack doesn't do a SW hash which is required for load balancing if the user decides to turn of rx-hashing on our device. This patch fixes the path so that we do not call skb_set_hash if the feature is disabled.

2016-01-08i40e: Look up MAC address in Open Firmware or IDPROMSowmini Varadhan
This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC address in Open Firmware or IDPROM"). As with that fix, attempt to look up the MAC address in Open Firmware on systems that support it, and use IDPROM on SPARC if no OF address is found. In the case of the i40e there is an assumption that the default mac address has already been set up as the primary mac filter on probe, so if this filter is obtained from the Open Firmware or IDPROM, an explicit write is needed via i40e_aq_mac_address_write() and i40e_aq_add_macvlan() invocation. The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure tracks whether a platform-specific mac address was found, in which case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan() will be triggered.

2016-01-08i40e: allow zero MAC address for VFsMitch Williams
Allow the user to specify a zero MAC address for VFs. This removes the existing MAC address and allows the VF to use a random address. Libvirt does this normally when removing a VF from a VM.

2016-01-08i40e: change log messages and error returnsMitch Williams
When VFs are being reset, there is a brief window of time when they cannot be configured because they don't have a VSI to configure. If a script is quick, it can fall through that window. To avoid defenestration, log a useful error message and return -EAGAIN.

2016-01-08brcmfmac: Do not handle link downs for ibss.Hante Meuleman
Sometimes on module reload and reconnect to ibss a deauth from other station can be received. This is treated as a link down but for ibss this is wrong. It will close the interface and no data is possible. Ignore the firmware generated link down events in ibss mode, as ibss is always teared down by cfg80211.

2016-01-08brcmfmac: use jiffies for timeout in btcoexArend van Spriel
The btcoex uses a timeout which was in milliseconds and got converted to jiffies upon using timer api. Instead, convert it to jiffies and treat it as such further.
