Hello everyone,
I would like to maximize the following function fqp with linear constraits
and the codes are as following:
a= c(0.2,0.3,0.4)
vcov=matrix(c(1,2,3,4,5,6,7,8,9),3,3)
fqp <- function(b) {t(b)%*%a-0.5*((t(b)%*%vcov)%*%b)}
constrOptim(c(b1,b2,b3), fqp,NULL,ui=?, ci=?, control=list(fnscale=-1))
The linear constrait is like abs(b1)+ abs(b2)+abs(b3)...

[PATCH 0/5] virtiofs: Fix couple of deadlocks
Hi,
We have couple of places which can result in deadlock. This patch series
fixes these.
We can be called with fc->bg_lock (for background requests) while
submitting a request. This leads to two constraints.
- We can't end requests in submitter's context and call fuse_end_request()
as it tries to take fc->bg_lock as well. So queue these requests on a
list and use a worker to
