2017-04-28staging: ks7010: fix enumeration tagsTobin C. Harding
Driver header declares enumeration types without tags. Using informative tags makes the code easier to understand and eliminates the need to comment the enum. Add tags to enumeration types. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-28staging: ks7010: add enum multicast_filter_typeTobin C. Harding
Driver uses preprocessor directives to define multicast filter constants. These can be defined using an enumeration type. Doing so adds to the readability and gives the assists the compiler.

2017-04-28staging: ks7010: continue from loop on unmatched macTobin C. Harding
Inside loop, code block is guarded with an 'if' statement. Instead of guarding the block we can invert the 'if' statement conditional and continue the loop. Doing so allows subsequent code indentation to be reduced and aids the readability of the code. Invert 'if' statement conditional, continue loop if new conditional evaluates to true. Reduce subsequent code indentation level. Do not change program logic. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-04-28staging: ks7010: make abbreviation mgmt uniformTobin C. Harding
Driver currently uses abbreviations 'mgt' and 'mngmt' for 'management'. Also 'power' is sometimes abbreviated to 'pow' and other times not. It makes the code easier to read and easier to modify if one abbreviation is used throughout the driver. 'mgmt' is widely accepted as an abbreviation of 'management'. 'power' can be spelled out in full, the extra two characters aids readability without an excessive cost. Make abbreviation of 'management' uniform across the driver, function names, preprocessor defined constants, and enumeration types. Signed-off-by: Tobin C.

2017-04-28staging: ks7010: add enum sleep_mode_typeTobin C. Harding
Driver uses preprocessor directives to define SLP_ASLEEP and SLP_ACTIVE. These can be defined using an enumeration type. Doing so adds to the readability and gives the usual compiler benefits of having an enum. Functions that currently accept integer types can now use the new enumeration type, further aiding readability. Add enumeration type sleep_mode_type. Update code that handles sleep mode to use the new enumeration type. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-28staging: ks7010: abstract connection statusTobin C. Harding
Host interface connection status is handled using a 32 bit type. Top byte is used as for FORCE_DISCONNECT status, low bits are used for connect/disconnect status. Driver masks and checks integers to ascertain status. If functions are defined to do the masking and equality check then the details of how the status integer is used are abstracted away. This makes the code easier to read. Also future updates to the status handling will be easier because the code is in one place. Driver currently uses the CONNECT_STATUS and DISCONNECT_STATUS as values, as apposed to opaque values. Because of this driver code checks for equality with CONNECT_STATUS and DISCONNECT_STATUS as apposed to negating a single check (ie 'foo != CONNECT_STATUS). In order to maintain the current functionality we define two separate functions is_connect_status() and is_disconnect_status(). Add functions to abstract the status integer check. Update all sites that do the check manually to use the newly defined functions. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-28staging: ks7010: add hostif_generic_request()Tobin C. Harding
Driver contains duplicate code. Host interface has numerous request functions which allocate memory for a request header. Each request header is different but all contain, as the first member, a hostif_hdr structure. This structure has size and event members which need to be set. By defining a helper function to allocate the memory and set the initial hostif_hdr members code duplication is reduced. Add function to allocate memory for a host interface request. Set 'size' and 'event' members. Remove duplicate code using newly defined function. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-28staging: ks7010: clean memory allocationTobin C. Harding
Memory allocation code contains unneeded debug statements, failed kmalloc() calls typically do not require a debug message. Introduction of a local 'size' variable allows kmalloc() call to be marginally cleaner, still uses magic numbers but these require a more substantial fix. Moving the magic numbers onto a single line opens the way for further refactoring. Clean memory allocation code, remove debug statements. Signed-off-by: Tobin C.

2017-04-28staging: ks7010: remove magic numbersTobin C. Harding
Driver includes magic numbers. Defining constants or using existing constants aids the readability of the code. Magic number '12' is used for two ethernet addresses (6 bytes each). ETH_ALEN is already defined within the kernel to 6. We can us the expression '2 * ETH_ALEN' to make this code explicit. Magic number '20' refers to the data size, in bytes, of a struct ether_hdr (described in eap_packet.h). We can define a constant for this purpose, making the code explicit and easier to read. Define constant. Remove magic numbers, using newly defined constant and/or expression using existing kernel constant. Signed-off-by: Tobin C.

2017-04-28staging: ks7010: move skb null check near allocationTobin C. Harding
Currently, after allocating an sk_buff, driver fills the sk_buff within code block guarded by a NULL check on the sk_buff. If a NULL check is done immediately after the allocation, and code returns on error, then the subsequent code need not be guarded and the level of indentation may be reduced. This aids the readability of the code and makes explicit the error path. Check for NULL directly after allocating the sk_buff, return if allocation fails. Reduce indentation of subsequent code. Do not change the program logic. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

omap_gpio_debounce() does not validate that the requested debounce is within a range it can handle. Instead it lets the register value wrap silently, and always returns success. This can lead to all sorts of unexpected behavior, such as gpio_keys asking for a too-long debounce, but getting a very short debounce in practice. Fix this by returning -EINVAL if the requested value does not fit into the register field. If there is no debounce clock available at all, return -ENOTSUPP.

2017-04-27dm mpath: delay requeuing while path initialization is in progressBart Van Assche
Requeuing a request immediately while path initialization is ongoing causes high CPU usage, something that is undesired. Hence delay requeuing while path initialization is in progress.

2017-04-27dm mpath: avoid that path removal can trigger an infinite loopBart Van Assche
If blk_get_request() fails, check whether the failure is due to a path being removed. If that is the case, fail the path by triggering a call to fail_path(). This avoids that the following scenario can be encountered while removing paths: * CPU usage of a kworker thread jumps to 100%. * Removing the DM device becomes impossible. Delay requeueing if blk_get_request() returns -EBUSY or -EWOULDBLOCK, and the queue is not dying, because in these cases immediate requeuing is inappropriate.

2017-04-27md/raid1: Use a new variable to count flighting sync requestsXiao Ni
In new barrier codes, raise_barrier waits if conf->nr_pending[idx] is not zero. After all the conditions are true, the resync request can go on be handled. But it adds conf->nr_pending[idx] again. The next resync request hit the same bucket idx need to wait the resync request which is submitted before. The performance of resync/recovery is degraded. So we should use a new variable to count sync requests which are in flight. I did a simple test: 1. Without the patch, create a raid1 with two disks. The resync speed: Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdb 0.00 0.00 166.00 0.00 10.38 0.00 128.00 0.03 0.20 0.20 0.00 0.19 3.20 sdc 0.00 0.00 0.00 166.00 0.00 10.38 128.00 0.96 5.77 0.00 5.77 5.75 95.50 2.

The patch adds necessary changes to the driver to use qed resource locking functionality. Currently the ptp initialization is spread between driver probe/open implementations, associated APIs are qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality into single API qed_ptp_enable() to simplify the usage of qed resource locking implementation. The new API will be invoked in the probe path. Similarly the ptp clean-up code is moved to qede_ptp_disable() which gets invoked in the driver unload path.
