Kyle Evans 2192cd125f imgact_binmisc: abstract away the list lock (NFC)
This module handles relatively few execs (initial qemu-user-static, then
qemu-user-static handles exec'ing itself for binaries it's already running),
but all execs pay the price of at least taking the relatively expensive
sx/slock to check for a match when this module is loaded. Future work will
almost certainly swap this out for another lock, perhaps an rmslock.

The RLOCK/WLOCK phrasing was chosen based on what the callers are really
wanting, rather than using the verbiage typically appropriate for an sx.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
