>Description:
[src/sbin/fsck_msdos/dir.c:988] -> [src/sbin/fsck_msdos/dir.c:989]: (performance) Buffer 'p' is being written before its old content has been used.
[src/sbin/fsck_msdos/dir.c:988] -> [src/sbin/fsck_msdos/dir.c:990]: (performance) Buffer 'p' is being written before its old content has been used.
Source code is
memset(p, 0, 32);
memset(p, ' ', 11);
memcpy(p, d.name, strlen(d.name));
Maybe better code
memset(p + 11, 0, 32 - 11);
memset(p, ' ', 11);
memcpy(p, d.name, strlen(d.name));
