debugfs_create_dir and debugfs_create_file may return -ENODEV when debugfs is not configured, so the return value should be checked against ERROR_VALUE as well, otherwise the later dereference of the dentry pointer would crash the kernel. This patch tries to solve this problem by fixing certain checks. However, I have that found other call sites are protected by #ifdef CONFIG_DEBUG_FS. In current implementation, if CONFIG_DEBUG_FS is defined, then the above two functions will never return any ERROR_VALUE. So another possibility to fix this is to surround all the buggy checks/functions with the same #ifdef CONFIG_DEBUG_FS. But I'm not sure if this would break any functionality, as only OCFS2_FS_STATS declares dependency on DEBUG_FS. Signed-off-by:

In ocfs2_local_alloc_find_clear_bits and ocfs2_get_dentry, variable numfound and set may be uninitialized and then used in tracepoint. In ocfs2_xattr_block_get and ocfs2_delete_xattr_in_bucket, variable block_off and xv may be uninitialized and then used in the following logic due to unchecked return value. This patch fixes these possible issues. Signed-off-by:

In ocfs2_direct_IO_write, we use ocfs2_zero_extend to zero allocated clusters in case of cluster not aligned. But ocfs2_zero_extend uses page cache, this may happen that it clears the data which blockdev_direct_IO has already written. We should use blkdev_issue_zeroout instead of ocfs2_zero_extend during direct IO. So fix this issue by introducing ocfs2_direct_IO_zero_extend and ocfs2_direct_IO_extend_no_holes. Reported-by:

Commit 61f77eda ("mm/hugetlb: reduce arch dependent code around follow_huge_*") broke follow_huge_pmd() on s390, where pmd and pte layout differ and using pte_page() on a huge pmd will return wrong results. Using pmd_page() instead fixes this. All architectures that were touched by that commit have pmd_page() defined, so this should not break anything on other architectures.

Pull regmap update from Mark Brown: "Just one patch for regmap this time around, a change from Steven Rostedt to prettify the way we're making the regmap internal header available to the trace events (it turns out that the trace subsystem doesn't actually need to be in trace/events)" * tag 'regmap-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Move tracing header into drivers/base/regmap
