[PATCH] tmpfs initial work

[Matthew Dillon]

:Hi,
:
:Now I'm trying to port NetBSD tmpfs to DragonFly, and I would like to
:share my progress with community.
:
:The attached patch is ported from Current NetBSD to master by myself,
:not the ones which post this mailing list before.
:It should be similar, but many parts should be different from.
:Please help me to finalize this tmpfs implementation, just apply the
:patch to current master git then report any issues you found.
:
: - add new vop APIs (ncreate nresolve etc)
: - passed initial test  mount, touch file, cp, ln, mknod ...
:
:todo:
: - still need to develop some sysctl to get swap page totals
:
:question:
:I see assertion error at kmalloc it say as following. Please give me
:some clues for this.
: panic: assertion: chunk->c_Next == NULL || ((intptr_t)chunk->c_Next &
:INSAME_PAGE_MASK) == ))intptr_t)chunk & IN_SAME_PAGE_MASK) in kmalloc
:mp_lock = 00000001; cpuid = 1

:thank you,

    Definitely memory corruption.  You are either using memory after you
    have freed it or you are using more memory then you allocated for
    a particular chunk.
