--- Comment #3 from Konstantin Belousov <[email protected]> --- No, si_refcount is not a reference existing during the mapping lifetime. The si_refcount is the transient refcount taken while a kernel thread operates on the cdev. For instance, in case of d_mmap, it is taken by dev_refthread() in old_dev_pager_fault() around the call to csw->d_mmap, and released by the nearby call(s) to dev_relthread(). -- You are receiving this mail because: You are the assignee for the bug.
