[LU-5991] memory leak on mount failure

• Type: Bug
• Resolution: Fixed
• Priority: Trivial
• Fix Version/s: Lustre 2.11.0
• Labels: patch
• Severity: 4
• Assignee: WC Triage
• Reporter: Vladimir V. Saveliev

Description

lustre_fill_super() allocates lsi and assumes that in case of failures server_fill_super() or ll_fill_super() will call server_put_super()/ll_put_super() to free the lsi. However,

• server_fill_super() misses that when lsi_prepare() fails.
• ll_fill_super() misses that when OBD_ALLOC_PTR(cfg) or
  ll_init_sbi() fail.
