2014-09-29gro: fix aggregation for skb using frag_listEric Dumazet1-0/+3
In commit 8a29111c7ca6 ("net: gro: allow to build full sized skb") I added a regression for linear skb that traditionally force GRO to use the frag_list fallback. Erez Shitrit found that at most two segments were aggregated and the "if (skb_gro_len(p) != pinfo->gso_size)" test was failing. This is because pinfo at this spot still points to the last skb in the chain, instead of the first one, where we find the correct gso_size information.

2014-09-29regmap: Fix debugfs-file 'registers' modeMarkus Pargmann1-1/+8
The macro "REGMAP_ALLOW_WRITE_DEBUGFS" can be used to enable write support on the registers file in the debugfs. The mode of the file is fixed to 0400 so it is not possible to write the file ever. This patch fixes the mode by setting it to the correct value depending on the macro. Signed-off-by: Markus Pargmann <[email protected]> Signed-off-by: Mark Brown <[email protected]>
2014-09-29spi: fsl: Sort include headers alphabeticallyXiubo Li5-36/+36
Sort all the include headers alphabetically for the freescale spi drivers. If the inlcude headers sorted out of order, maybe the best logical choice is to append new ones after the exist ones, while this may create a lot of potential for duplicates and conflicts for each diffenent changes will add new headers in the same location.

2014-09-27vfs: Don't exchange "short" filenames unconditionally.Mikhail Efremov1-9/+18
Only exchange source and destination filenames if flags contain RENAME_EXCHANGE. In case if executable file was running and replaced by other file /proc/PID/exe should still show correct file name, not the old name of the file by which it was replaced. The scenario when this bug manifests itself was like this: * ALT Linux uses rpm and start-stop-daemon; * during a package upgrade rpm creates a temporary file for an executable to rename it upon successful unpacking; * start-stop-daemon is run subsequently and it obtains the (nonexistant) temporary filename via /proc/PID/exe thus failing to identify the running process. Note that "long" filenames (> DNAiME_INLINE_LEN) are still exchanged without RENAME_EXCHANGE and this behaviour exists long enough (should be fixed too apparently). So this patch is just an interim workaround that restores behavior for "short" names as it was before changes introduced by commit da1ce0670c14 ("vfs: add cross-rename"). See https://lkml.org/lkml/2014/9/7/6 for details. AV: the comments about being more careful with ->d_name.hash than with ->d_name.name are from back in 2.3.40s; they became obsolete by 2.3.60s, when we started to unhash the target instead of swapping hash chain positions followed by d_delete() as we used to do when dcache was first introduced.
