2016-04-28Documentation: fix common spelling mistakesKees Cook23-29/+30
This fixes several spelling mistakes in the Documentation/ tree, which are caught by checkpatch.pl's spell checking. Signed-off-by: Kees Cook <keescook@chromium.org> Reviewed-by: Paul E.

2016-04-28samples: v4l: from Documentation to samples directoryArnd Bergmann5-4/+3
A small bug with the new autoksyms support showed that there are two kernel modules in the Documentation directory that qualify as samples, while all other samples are in the samples/ directory. This patch was originally meant as a workaround for that bug, but it has now been solved in a different way. However, I still think it makes sense as a cleanup to consolidate all sample code in one place.

2016-03-26f2fs/crypto: fix xts_tweak initializationLinus Torvalds1-1/+1
Commit 0b81d07790726 ("fs crypto: move per-file encryption from f2fs tree to fs/crypto") moved the f2fs crypto files to fs/crypto/ and renamed the symbol prefixes from "f2fs_" to "fscrypt_" (and from "F2FS_" to just "FS" for preprocessor symbols). Because of the symbol renaming, it's a bit hard to see it as a file move: use git show -M30 0b81d07790726 to lower the rename detection to just 30% similarity and make git show the files as renamed (the header file won't be shown as a rename even then - since all it contains is symbol definitions, it looks almost completely different). Even with the renames showing as renames, the diffs are not all that easy to read, since so much is just the renames. But Eric Biggers noticed that it's not just all renames: the initialization of the xts_tweak had been broken too, using the inode number rather than the page offset. That's not right - it makes the xfs_tweak the same for all pages of each inode. It _might_ make sense to make the xfs_tweak contain both the offset _and_ the inode number, but not just the inode number.

The offending functions implement an optional part of the api, so they are removed. They can be added later, after testing.

2016-03-26orangefs: fix orangefs_superblock lockingAl Viro3-58/+47
* switch orangefs_remount() to taking ORANGEFS_SB(sb) instead of sb * remove from the list _before_ orangefs_unmount() - request_mutex in the latter will make sure that nothing observed in the loop in ORANGEFS_DEV_REMOUNT_ALL handling will get freed until the end of loop * on removal, keep the forward pointer and zero the back one. That way we can drop and regain the spinlock in the loop body (again, ORANGEFS_DEV_REMOUNT_ALL one) and still be able to get to the rest of the list.
