Subject: [PATCH 49/86] src/check.c: Fix up mtools created bad dir entries
|
|
|
|
mtools writes uninitialized data to the case field of some
|
|
directory entries. Running fsck.fat on these filesystems
|
|
will cause the directory to get deleted which can lead to
|
|
data loss. Detect this situation and clear the flag instead.
|
|
|
|
mtools patch to fix the original issue:
