[LU-8339] Lock improvement for kiblnd_check_sends

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.9.0
• Assignee: Doug Oucharek (Inactive)
• Reporter: Doug Oucharek (Inactive)

Description

kiblnd_check_sends() takes conn::ibc_lock at the beginning and releases this lock at the end. This is inefficient because most use-cases needs to release ibc_lock before caling this function.

Change this function to kiblnd_check_sends_locked() and avoid unnecessary lock dances.
