[PATCH 0/1] smb3: Memory leak/page refcount overflow fix

Posted by David Howells 3 years, 1 month ago

Hi Steve,

Here's another fix patch for you.  It fixes a leak of the pages extracted
for direct I/O.  This was causing the page refcount to overflow and become
negative and then try_grab_page() would always fail on it.

I've pushed the patch here also:
