LGTM.

Mehakmeet, you don't need to get a +1 on a simple backport, seeing that yetus is happy is enough. if it's complicate it is still good to get some review, but only looking for risk of regressions, rather than any major change

[mehakmeet]

@steveloughran Noted. Wanted to double-check since this has a commented-out bit from the trunk changes. Wanted to see if this was within the coding standard(having a TODO comment in production code). Thanks for letting me know.

[steveloughran]

you need to cherrypick to the branch-3.3.5 branch too

[mukund-thakur]

Cherrypicked this one in branch-3.3.5 @mehakmeet thank me later :P

[mehakmeet]

@mukund-thakur Thanks! 😄
