mem-pool: Restructure mem-pool behaviour 2009-05-19T15:43:22+00:00 Shehjar Tikoo shehjart@gluster.com 2009-05-19T04:34:11+00:00 a9d0be4f1b78d9c03e9379fc5cea0ead6114c1d0 This commit changes mem-pool behaviour to return a directly usable address by performing the required adjustment on the address being returned. This is different from the previous behaviour where we're trying to fit into the requested size, the list_head*2 also. This is not efficient enough in terms of space but hopefully works better than not having any mem-pool at all. Besides, I am not comfortable with mem-pool meta-data and caller-useable memory area being the same because of the potential for mem-pool's data structure corruption.
