CVE-2026-98269
In the Linux kernel, the following vulnerability has been resolved:

btrfs: abort transaction on failure to update inode for hole punching and reflinking

If we fail to update the inode we error out without aborting the
transaction, which can result in a persistent inconsistency if after
the failure the transaction is committed, as we have dropped file
extent items from a range and either punched a hole or insert a new file
extent item for that range (for reflinks).

So add the missing transaction abort.
