[LU-5631] Incorrect swabbing of struct llog_rec_tail

• Type: Bug
• Resolution: Fixed
• Priority: Major
• Fix Version/s: Lustre 2.7.0, Lustre 2.5.4
• Affects Version/s: Lustre 2.7.0
• Labels: patch
• Severity: 3
• Assignee: James Nunez (Inactive)
• Reporter: Henri Doreau (Inactive)

Description

llog_rec_tail is accessed directly (tail = &cr->cr_tail) in lustre_swab_llog_rec, though it comes after a variable length structure. This lead to the cr_name field of the changelog_record being shuffled and the actual tail being left untouched...
