f2fs-tools: Fix various compilation warnings
Avoid various compilation warnings due to strncpy:
libf2fs.c:590:33: warning: ‘snprintf’ output may be truncated before
the last format character [-Wformat-truncation=]
snprintf(rootdev, ret, "/dev/%s", buf);
../include/f2fs_fs.h:1384:2: warning: ‘strncpy’ specified bound
depends on the length of the source argument [-Wstringop-overflow=]
strncpy(buf, features, strlen(features) + 1);
f2fstat.c:243:3: warning: ‘strncpy’ output truncated before
terminating nul copying as many bytes from a string as its length
[-Wstringop-truncation]
strncpy(ptr_buf, name[i], strlen(name[i]));
This patch does not change any functionality.
