Doc Text: |
A problem with the XFS dio error handling was discovered. If a misaligned write I/O operation was issued, XFS would return -EINVAL without unlocking the inode's mutex. This caused any further operations on the inode to become unresponsive. This update adds a missing mutex_unlock operation to the dio error path, solving this issue.
