Hi Experts, See drivers/md/dm-bufio.c as below: 50 /* 51 * Buffer hash 52 */ 53 #define DM_BUFIO_HASH_BITS 20 54 #define DM_BUFIO_HASH(block) \ 55 ((((block) >> DM_BUFIO_HASH_BITS) ^ (block)) & \ 56 ((1 << DM_BUFIO_HASH_BITS) - 1)) "drivers/md/dm-bufio.c" 1854L, 45375C DM_BUFIO_HASH_BITS was defined as 20 and it maybe not fit for some use case with limited resources. Do we have any plan to make it more flexible? Like module parameter or something else?
