Обсуждение: Unused MMCacheLock

Hi,

Are there any reasons MMCacheLock has been left yet?
Did we forget to remove it when mm.c was removed?

Not as far as I can see -- good catch. Patch applied to HEAD.

Neil,

I thought you removed that in February? Or is my memory playing tricks?

Not I -- Tom removed src/backend/storage/smgr/mm.c in February of '04,
but evidently forgot to remove the associated LWLock.
