CVE-2026-98269
btrfs: abort transaction on failure to update inode for hole punching and reflinking
Description
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.
