New Revision: 285596
URL: https://svnweb.freebsd.org/changeset/base/285596
Log:
Make posix_fallocate() and posix_fadvise() work.
We can map these system calls directly to the FreeBSD counterparts. The
other filesystem related system calls will be sent out for review
separately, as they are a bit more complex to get right.
