collecting garbage in two phases: in the first stage, with
alldevs_mtx held, gather all of the objects to be freed onto a
list. Drop alldevs_mtx, and in the second stage, free all the
collected objects.
Also per rmind@'s suggestion, remove KASSERT(!mutex_owned(&alldevs_mtx))
throughout, it is not useful.
Find a free unit number and allocate it for a new device_t atomically.
Before, two threads would sometimes find the same free unit number
and race to allocate it. The loser panicked. Now there is no
race.
In support of the changes above, extract some new subroutines that
are private to this module: config_unit_nextfree(), config_unit_alloc(),
config_devfree(), config_dump_garbage().
Delete all of the #ifdef __BROKEN_CONFIG_UNIT_USAGE code. Only
the sun3 port still depends on __BROKEN_CONFIG_UNIT_USAGE, it's
not hard for the port to do without, and port-sun3@ had fair warning
that it was going away (>1 week, or a few years' warning, depending
how far back you look!).
as xkbd backend. This problem was reported by Hugo Silva on port-xen.
Now we call DIOCGWEDGEINFO for all partitions, when it is not implemented
we use DIOCGPART to get information about volume size.
Fix oked by jym@.
Apart from infrastructure changes, there are the following functional ones:
+ Update to version 20091210
+ provide a new netpgp_match_list_keys(3) function to perform a
regular-expression based search of all the keys in the keyring. If no
pattern is specified to match, then all keys are returned.
+ provide a new netpgp_set_homedir(3) function, and use it to set the
home directory from the library, rather than individually in all the
programs which use the library
+ provide a new netpgp_incvar(3) function which will add a constant
increment (which may be negative) to the value of an internal
variable. This is primarily used for the verbosity level within the
library, and is again a movement of the function into the library from
the individual programs which use the library
+ move to the specification of an ssh key file by internal variable,
rather than the directory holding an ssh key file
+ autoconf infrastructure changes
+ take a hammer to the _GNU_SOURCE definitions problems
+ don't rely on strnlen(3) being present everywhere
