These are things that I would like to eventually get done. Please mail me if you'd like to work on them.

Merge fdescfs into devfs.

• needed for fexecve()+shebang
• expected by lots of third-party software
• default in other unix-like kernels
• considerations:
  • needs to appear in jails by default as well
  • need to sort out Capsicum integration

Early microcode loading on AMD

• lacking a convenient test system

TRIM for swap devices

• interrogate swap GEOM for candelete capability
• dispatch TRIMs asynchronously from swp_pager_freeswapspace()
• maybe not so important now that we use a next-fit block allocation policy instead of first-fit? (See r320077.)

IPv6 netdump(4)

• need to use Neighbour Discovery to find the first-hop router

Kernel dump regression testing

• doable with bhyve and expect after r346550

lockmgr(9), rmlock(9) and epoch(9) integration into lockstat

• False-positive WITNESS warnings. These confuse automation and new users alike.
• stack_chk_init: WARNING: Initializing stack protection with non-random cookies!
  • I don't know whether this is important or how to fix it.

Set a Kyua configuration variable from the command line

• kyua -v test_suites.FreeBSD.allow_sysctl_side_effects=1 test
