2014-01-26i2c: update i2c_algorithm documentationBen Dooks
Add some kerneldoc style documentaton to the i2c_algorithm structure, and point the master_xfer return codes at the right place in Documentation/i2c/fault_codes Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-01-26i2c: rcar: use devm_clk_get to ensure clock is properly ref-countedBen Dooks
The current i2c-rcar driver does clk_get() without a corresponding clk_put(). Add the clk to the driver private data and then get it with the devm functions so that it is released when the driver is unbound. Note, we do not call clk_prepare_enable() at this point due to the very possible magic that is being done by the pm_runtime system underneath the driver.

2014-01-26i2c: rcar: do not print error if device nacks transferBen Dooks
The i2c-rcar driver currently prints an error message if the master_xfer callback fails. However if the bus is being probed then lots of NAKs will be generated, causing the output of a number of errors printed. To solve this, disable the print if the error is not -EREMOTEIO. An example of running i2cdetect: 10: i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 -- 12 i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 -- i2c-rcar e6530000.i2c: error -121 : 15 Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2014-01-26vfs: Remove second variable named error in __dentry_pathEric W. Biederman

2014-01-26Fix race when checking i_size on direct i/o readSteven Whitehouse
So far I've had one ACK for this, and no other comments. So I think it is probably time to send this via some suitable tree. I'm guessing that the vfs tree would be the most appropriate route, but not sure that there is one at the moment (don't see anything recent at kernel.org) so in that case I think -mm is the "back up plan". Al, please let me know if you will take this? Steve. --------------------- Following on from the "Re: [PATCH v3] vfs: fix a bug when we do some dio reads with append dio writes" thread on linux-fsdevel, this patch is my current version of the fix proposed as option (b) in that thread. Removing the i_size test from the direct i/o read path at vfs level means that filesystems now have to deal with requests which are beyond i_size themselves. These I've divided into three sets: a) Those with "no op" ->direct_IO (9p, cifs, ceph) These are obviously not going to be an issue b) Those with "home brew" ->direct_IO (nfs, fuse) I've been told that NFS should not have any problem with the larger i_size, however I've added an extra test to FUSE to duplicate the original behaviour just to be on the safe side. c) Those using __blockdev_direct_IO() These call through to ->get_block() which should deal with the EOF condition correctly. I've verified that with GFS2 and I believe that Zheng has verified it for ext4. I've also run the test on XFS and it passes both before and after this change. The part of the patch in filemap.c looks a lot larger than it really is - there are only two lines of real change. The rest is just indentation of the contained code. There remains a test of i_size though, which was added for btrfs. It doesn't cause the other filesystems a problem as the test is performed after ->direct_IO has been called. It is possible that there is a race that does matter to btrfs, however this patch doesn't change that, so its still an overall improvement.

This changes the existing behaviour: - for buffers (ceph_buffer_new()), from trying to kmalloc() everything and using vmalloc() just as a fallback - for messages (ceph_msg_new()), from going to vmalloc() for anything bigger than a page - for messages (ceph_msg_new()), from disallowing vmalloc() to use high memory Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com> Reviewed-by: Sage Weil <sage@inktank.com>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "A respun version of the merges for the pull request previously sent with a few additional fixes. The last two merges were fixed up by hand since the branches have moved on and currently have the prior merge in them. Quite a busy release for the SPI subsystem, mostly in cleanups big and small scattered through the stack rather than anything else: - New driver for the Broadcom BC63xx HSSPI controller - Fix duplicate device registration for ACPI - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA changes upon which the transiton depends) - Some small optimisations to reduce the amount of time we hold locks in the datapath, eliminate some redundant checks and the size of a spi_transfer - Lots of fixes, cleanups and general enhancements to drivers, especially the rspi and Atmel drivers" * tag 'spi-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (112 commits) spi: core: Fix transfer failure when master->transfer_one returns positive value spi: Correct set_cs() documentation spi: Clarify transfer_one() w.r.t. spi_finalize_current_transfer() spi: Spelling s/finised/finished/ spi: sc18is602: Convert to use bits_per_word_mask spi: Remove duplicate code to set default bits_per_word setting spi/pxa2xx: fix compilation warning when !CONFIG_PM_SLEEP spi: clps711x: Add MODULE_ALIAS to support module auto-loading spi: rspi: Add missing clk_disable() calls in error and cleanup paths spi: rspi: Spelling s/transmition/transmission/ spi: rspi: Add support for specifying CPHA/CPOL spi/pxa2xx: initialize DMA channels to -1 to prevent inadvertent match spi: rspi: Add more QSPI register documentation spi: rspi: Add more RSPI register documentation spi: rspi: Remove dependency on DMAE for SHMOBILE spi/s3c64xx: Correct indentation spi: sh: Use spi_sh_clear_bit() instead of open-coded spi: bitbang: Grammar s/make to make/to make/ spi: sh-hspi: Spelling s/recive/receive/ spi: core: Improve tx/rx_nbits check comments ...

Pull networking updates from David Miller: 1) BPF debugger and asm tool by Daniel Borkmann. 2) Speed up create/bind in AF_PACKET, also from Daniel Borkmann. 3) Correct reciprocal_divide and update users, from Hannes Frederic Sowa and Daniel Borkmann. 4) Currently we only have a "set" operation for the hw timestamp socket ioctl, add a "get" operation to match. From Ben Hutchings. 5) Add better trace events for debugging driver datapath problems, also from Ben Hutchings. 6) Implement auto corking in TCP, from Eric Dumazet. Basically, if we have a small send and a previous packet is already in the qdisc or device queue, defer until TX completion or we get more data. 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko. 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel Borkmann. 9) Share IP header compression code between Bluetooth and IEEE802154 layers, from Jukka Rissanen. 10) Fix ipv6 router reachability probing, from Jiri Benc. 11) Allow packets to be captured on macvtap devices, from Vlad Yasevich. 12) Support tunneling in GRO layer, from Jerry Chu. 13) Allow bonding to be configured fully using netlink, from Scott Feldman. 14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can already get the TCI. From Atzm Watanabe. 15) New "Heavy Hitter" qdisc, from Terry Lam. 16) Significantly improve the IPSEC support in pktgen, from Fan Du. 17) Allow ipv4 tunnels to cache routes, just like sockets. From Tom Herbert. 18) Add Proportional Integral Enhanced packet scheduler, from Vijay Subramanian. 19) Allow openvswitch to mmap'd netlink, from Thomas Graf. 20) Key TCP metrics blobs also by source address, not just destination address. From Christoph Paasch. 21) Support 10G in generic phylib. From Andy Fleming. 22) Try to short-circuit GRO flow compares using device provided RX hash, if provided. From Tom Herbert. The wireless and netfilter folks have been busy little bees too. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (2064 commits) net/cxgb4: Fix referencing freed adapter ipv6: reallocate addrconf router for ipv6 address when lo device up fib_frontend: fix possible NULL pointer dereference rtnetlink: remove IFLA_BOND_SLAVE definition rtnetlink: remove check for fill_slave_info in rtnl_have_link_slave_info qlcnic: update version to 5.3.55 qlcnic: Enhance logic to calculate msix vectors. qlcnic: Refactor interrupt coalescing code for all adapters. qlcnic: Update poll controller code path qlcnic: Interrupt code cleanup qlcnic: Enhance Tx timeout debugging. qlcnic: Use bool for rx_mac_learn. bonding: fix u64 division rtnetlink: add missing IFLA_BOND_AD_INFO_UNSPEC sfc: Use the correct maximum TX DMA ring size for SFC9100 Add Shradha Shah as the sfc driver maintainer. net/vxlan: Share RX skb de-marking and checksum checks with ovs tulip: cleanup by using ARRAY_SIZE() ip_tunnel: clear IPCB in ip_tunnel_xmit() in case dst_link_failure() is called net/cxgb4: Don't retrieve stats during recovery ...
