Subject: runtime: add vgetrandom lock rank
X-Git-Tag: go1.25rc1~40
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=7b4d065267aec8f899a5c5423c1ac501d31807cc;p=gostls13.git

runtime: add vgetrandom lock rank

vgetrandomGetState can call malloc, so this is not a leaf lock.

Our staticlockrank builder doesn't support vgetrandom, so it didn't
catch this.
