In the linux kernel 'current' is defined to mean the current process
and can never be used as a local variable in a function. Simply
replace all usage of 'current' with 'curr' in this function.
This is a portability change which removes the dependence of the Solaris
thread library. All locations where Solaris thread API was used before
have been replaced with equivilant Solaris kernel style thread calls.
In user space the kernel style threading API is implemented in term of
the portable pthreads library. This includes all threads, mutexs,
condition variables, reader/writer locks, and taskqs.
Updated fix to detect if we are in an interrupt and only sleep if it
is safe to do some. I guess it must be safe to sleep under Solaris
this must be handled in a sort interrupt handler there
Added print_timestamp() compatibility function, this will be needed
long term but it's a simply enough addition.
Added Solaris style label functions. This was done simply to aid in
the initial update to onnv_141. I'm hopeful that after more careful
inspection all of this can be removed and we can integrate with a
more Linux friendly Solution without breaking any compatibility.
Added several missing headers which are required by the updated
version of ZFS. As usual I just add empty headers if needed because
it's easier than tracking the change against the core ZFS code.
Added SEC, MILLISEC, MICROSEC defines if unavailable.
Added missing xuio structure and typedefs. I'm hopeful these can
be removed as well once we crack the zero-copy nut under Linux.
Almost exclusively this patch handled the addition of another char
array to the zfs_cmd_t structure. Unfortunately c90 doesn't allow
zero filling the entire struct with the '= { 0 };' shorthand.
Originally these changes were on other gcc-* topic branches but
because c90 touches the same bit of code and I'd like to keep all
the gcc-* branches completely parallel I've moved these few bits
over here. This is one of the downsides of not just having one
big patch stack.
Fix new instances or changes in gcc flagged unused code. These are
mostly related to variables which are not used when debugging is
disabled and the ASSERTs are compiled out.
