-Subject: [PATCH] cifs: fix dentry refcount leak when opening a FIFO on lookup
-
-The cifs code will attempt to open files on lookup under certain
-circumstances. What happens though if we find that the file we opened
-was actually a FIFO or other special file?
-
-Currently, the open filehandle just ends up being leaked leading to
-a dentry refcount mismatch and oops on umount. Fix this by having the
-code close the filehandle on the server if it turns out not to be a
-regular file. While we're at it, change this spaghetti if statement
-into a switch too.
