[DragonFlyBSD - Bug #2336] 3.0.3 catchall

[Venkatesh Srinivas via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2336 has been updated by Venkatesh Srinivas.


Status ===

--- open:

* Bug 2296 ('pmap wire_count assertion in i386 VM') is still open, but dillon has started working on it after recently reproducing it on pkgbox32
* Bug 2349 ('Don't create zombies when SIGCHLD is sig_ign-ed') was linked because the bug affects 3.0 and there is a patchset. 

--- To MFC:

* Bug 2338 ('vm_pageout_scan active sees null object') is still open, but a fix has been commited to -master that should resolve it (19cd98ea71f56117435402874beedbdf6d399b52). After more digestion, it should be MFC-ed.
* Bug 2341 ('HAMMER rb comparison in multivolume incorrect') remains open. There is a patch, committed to -master (41a8e51772c65775f6b34c29ececa01178e633b9), that should be MFCed.

---
After that range of fixes, perhaps there should be a 3.0.3 release? There have been a lot of nice fixes into the DragonFly_RELEASE_3_0 branch since the 3.0.2 release. 

None are absolutely required to successfully install, except in rare cases (specifically -- soft updates fixes; there was one report of panics during install in the softdep code). But the fixes are all 'nice to have', I think, particularly for sites that run only numbered releases rather than the head of DragonFly_RELEASE_3_0 branch.

--- Extra:
There has now been a report of corruption on a HAMMER volume; specifically of hex '0's being appended to a file after a clean unmount; also of file changes long before shutdown long surviving a reboot. This should be investigated in -master. Till then I think a 3.0.3 release should be blocked, as it gained the clustering fixes from -master.

There has been a report of a panic in soft-updates also, via the fsync path. Some more work there is called for; it is also time to eliminate the MPlock in soft updates.
