The patch titled Subject: mm/kmemleak.c: record the current memory pool size has been removed from the -mm tree. Its filename was mm-kmemleak-record-the-current-memory-pool-size.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Qian Cai <cai@xxxxxx> Subject: mm/kmemleak.c: record the current memory pool size The only way to obtain the current memory pool size for a running kernel is to check the kernel config file which is inconvenient. Record it in the kernel messages.
