Attached patch patch for tip — — Splinter Review
Comment on attachment 120728 [details] [diff] [review] patch for tip Note that pkcs11 contexts need to have parameters set, even if they are not empty. To avoid both the zero-byte memcpy and a wasted malloc, I create a static set of NULL params.
Attachment #120728 - Flags: review?(relyea)
This patch has the exact same content as the other patch, but applies cleanly to the 3.3 branch (some things moved around).
Comment on attachment 120728 [details] [diff] [review] patch for tip looks good.
