From a8803055279e3039285f7ede461a4dd90a93ea3e Mon Sep 17 00:00:00 2001 From: Ashutosh Bapat Date: Tue, 26 Aug 2025 18:34:39 +0530 Subject: [PATCH] Mark shared buffer lookup table has fixed_buf_table StrategyInitialize() calls InitBufTable() with maximum number of entries that the buffer lookup table can ever have. Thus there should not be any need to allocate more element after initialization. Hence mark the hash table as fixed sized.
