From 198729c9627a754b26aebdc8a26e559424c8f06c Mon Sep 17 00:00:00 2001 From: Kassey Li Date: Tue, 19 Jul 2022 17:15:54 +0800 Subject: mm/cma_debug.c: align the name buffer length as struct cma Avoids truncating the debugfs output to 16 chars. Potentially alters the userspace output, but this is a debugfs interface and there are no stability guarantees.
