 My vision of the problem in short: when user tries to access to the memory backed by tmpfs first time, kernel asks defpager to initialize memory object and sets it's request port to some value. But sometimes user directly accesses to defpager and supplies it own request port. So defpager should handle different request port, what causes errors.
 
+TODO: pager_extend always frees old pagemap and allocates new. Consider if it is necessary.

 ## Steps
 
 ### Find out what causes crashes in tmpfs with defpager
