    Subject[PATCH 0/2] msync improvements
    Date
    These two patches are improvements on the implementation of the msync
    system call. To give some context, I found them while working on
    the implementation of a persistent dirty bitmap.

    Paolo Bonzini (2):
    msync: support syncing a small part of the file
    msync: start async writeout when MS_ASYNC
