[LU-2071] Memory leak in procfs handling

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.4.0
• Severity: 3

Description

There seems to be a minor memory leak in all versions of lustre since at least Feb 2007.

The name##_seq_open does single_open, but corresponding lprocfs_seq_release does seq_release instead of single_release, and as such a bit of memory allocated in single_open remains not freed.
As such every call to lctl leaks 32 bytes.
