GFS2: Improve bug trap code in ->releasepage() If the buffer is dirty or pinned, then as well as printing a warning, we should also refuse to release the page in question. Currently this can occur if there is a race between mmap()ed writers and O_DIRECT on the same file. With the addition of ->launder_page() in the future, we should be able to close this gap.
