7abb0b0922 Don't specify a resid parameter if we're just going to ignore it. Instead,
let vn_rdwr() check for short reads.

250246706f Free the zlib stream after expanding a compressed CTF section.
Note that this memory would only be leaked once, since CTF info for a kld
file is cached after the first access.

5050aa86cf Remove the support for using non-mpsafe filesystem modules.
In particular, do not lock Giant conditionally when calling into the
filesystem module, remove the VFS_LOCK_GIANT() and related
macros. Stop handling buffers belonging to non-mpsafe filesystems.

The VFS_VERSION is bumped to indicate the interface change which does
not result in the interface signatures changes.

526d0bd547 Fix found places where uio_resid is truncated to int.
Add the sysctl debug.iosize_max_clamp, enabled by default. Setting the
sysctl to zero allows to perform the SSIZE_MAX-sized i/o requests from
the usermode.

6f6924e5a6 The in-kernel CTF parser caches the result of its first attempt to parse
CTF data from a module.  On subsequent attempts to retrieve CTF data for
a module, return an error if there no CTF data.

This fixes a panic if you try to enable fbt probes on a module with CTF
data twice.
