-Subject: [PATCH] Fix access to the dentry
-
-Since Linux 2.6.20, the dentry pointer is no longer stored in
-file->f_dentry, but in file->f_path.dentry. Until Linux 3.19, there
-was a compatibility macro which made the change transparent, but this
-macro has now been removed.
-
-Since we probably don't care about compatibility with kernels older
-than 2.6.20, this commit takes the simple approach of using
-file->f_path.dentry. This will work with any kernel >= 2.6.20.
-
-Submitted upstream at https://github.com/nicupavel/emlog/pull/3.
