Hi, Header says: /* * Unmaps the @count pages starting at @start_address, which were mapped by a * call to xc_gntshr_share_*. Never logs. */ int xc_gntshr_munmap(xc_gntshr *xcg, void *start_address, uint32_t count); But implementation calls: static int linux_gntshr_munmap(xc_gntshr *xcg, xc_osdep_handle h, void *start_address, uint32_t count) { return

Hi all: This series try to fix several issues introduced by meta data accelreation series. Please review. Changes from V1: - Try not use RCU to syncrhonize MMU notifier with vhost worker - set dirty pages after no readers - return -EAGAIN only when we find the range is overlapped with metadata Jason Wang (9): vhost: don't set uaddr for invalid address vhost: validate MMU notifier
