[PATCH 02/12] vfs: More precise tests in d_invalidate

2014-02-25 Thread Eric W. Biederman
The current comments in d_invalidate about what and why it is doing what it is doing are wildly off-base. Which is not surprising as the comments date back to last minute bug fix of the 2.2 kernel. The big fat lie of a comment said: If it's a directory, we can't drop it for fear of somebody
