No description provided.

eg. recvmsg, the buf address may be in mprotect, the kernel would return err.
We have to hook the system call and retry :(.

Hi @kyoguan! Thanks for this, and sorry for the very long delay.

I cherry-picked two of the commits that were clear bug fixes (the FD leak and recv rely bits).

For making fork faster, I believe that not using the bitmap will undo the physical memory savings we gain by meshing -- in other words I think the 8x speed improvement comes at the cost of losing our reclaimed/meshed memory. I think ideally we would have a unit test here to verify the RSS of the child after fork. Maybe I am misunderstanding though!
