This triggers\nwhen the user reads from /dev/hwrng into memory also mmap-ed from\n/dev/hwrng.  The resulting page fault triggers a recursive read\nwhich then dead-locks.\n\nFix this by using a stack buffer when calling copy_to_user."

Esto se activa cuando el usuario lee desde /dev/hwrng en la memoria y tambi\u00e9n realiza mmap-ed desde /dev/hwrng. El error de p\u00e1gina resultante desencadena una lectura recursiva que luego se bloquea. Solucione este problema utilizando un b\u00fafer de pila al llamar a copy_to_user."
