Subject: fsck: don't free fstab table on parse failure
X-Git-Tag: v2.22-rc1~553

fsck: don't free fstab table on parse failure

Even if we fail parsing, fstab gets referenced later in the code (and
will subsequently crash via heap corruption). Take the easy way out and
simply avoid deallocating this table, as it will be freed for us on
program exit regardless.
