Seems that I will break the quietness :)
To my project, I will use a file as the swap area first. Since it's a file, I
can use the facilities provided by the filesystem.
On modifying the vm_store_anonymous_noswap, a member: struct vnode * vnode
(represents the swap file) will be added to the anonymous_store stuct. And the
store_anonymous operation functions will be very like those in vnode_store. Am
I right?
I am confused by the word "commit". Does it equal "use"? Could anyone explain
those fields in the anonymous_store struct:
bool can_overcommit;
bool has_precommitted;
uint8 precommitted_pages;
int32 guarded_size;
Thanks!
