Subject: mm/cma_debug.c: align the name buffer length as struct cma
X-Git-Tag: remove_vma_adjust~16
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=db2c533bc6fdd4ff95ab2024c328922ac1d7b8a0;p=users%2Fjedix%2Flinux-maple.git

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.
