I recently started seeing the warning message:
/usr/src/sys/vm/uma_core.c:1332: could sleep with "kernel linker" locked
from /usr/src/sys/kern/kern_linker.c:1797
at boot time on my -current box. It appears to be related to the
changes in rev 1.90 of kern_linker.c.
I suspect that memory is getting allocted inside this loop in
sysctl_kern_function_list():
mtx_lock(&kld_mtx);
TAILQ_FOREACH(lf, &linker_files, link) {
error = LINKER_EACH_FUNCTION_NAME(lf,
sysctl_kern_function_list_iterate, req);
if (error) {
mtx_unlock(&kld_mtx);
return (error);
}
}
mtx_unlock(&kld_mtx);
but I got lost in a maze of twisty little passages.
And where the heck is LINKER_EACH_FUNCTION_NAME defined? This is the
only occurence of this string in the entire /usr/src tree ...
