[PATCH] mm: schedule find_trylock_page() removal
find_trylock_page() is an odd interface in that it doesn't take a reference like the others. Now that XFS no longer uses it, and its last remaining caller actually wants an elevated refcount, opencode that callsite and schedule find_trylock_page() for removal.

+What: find_trylock_page
+When: January 2007
+Why: The interface no longer has any callers left in the kernel. It
+ is an odd interface (compared with other find_*_page functions), in
+ that it does not take a refcount to the page, only the page lock.
+ It should be replaced with find_get_page or find_lock_page if possible.
+ This feature removal can be reevaluated if users of the interface
+ cannot cleanly use something else.
