[16937.192225] F2FS-fs (loop0): Mount Device [ 0]: /mnt/f2fs/012345678901234567890123456789012345678901234567890123\xff\x01, 511, 0 - 3ffff
[16937.192268] F2FS-fs (loop0): Failed to find devices
If device path length equals to MAX_PATH_LEN, sbi->devs.path[] may
not end up w/ null character due to path array is fully filled, So
accidently, fields locate after path[] may be treated as part of
device path, result in parsing wrong device path.
struct f2fs_dev_info {
...
char path[MAX_PATH_LEN];
...
};
Let's add one byte space for sbi->devs.path[] to store null
character of device path string.
