:> Log:
:> Drop filedesc lock and acquire Giant around calls to malloc() and free().
:> These call uma_large_malloc() and uma_large_free() which require Giant.
:> Fixes panic when descriptor table is larger than KMEM_ZMAX bytes
:> noticed by kkenn.

:What about things like geom which explicitly call malloc without Giant?
:Or is it just a problem for large allocations?

:Cheers,

Perhaps I am reading this wrong, but does this imply that the API
for malloc() has different requirements depending on the size of
the allocation? That doesn't make much sense to me.
