Hi,
I've found some possible deadlock in fs/ocfs2/dlm/dlmmaster.c - version
2.6.28 (probably this code is in newer versions too).
Could someone confirm this? Thank you.
fs/ocfs2/dlm/dlmmaster.c
==================
function dlm_master_request_handler: (res->spinlock <- dlm->master_lock)
-----------------------------------
spin_lock(&res->spinlock); at line 1427
spin_lock(&dlm->master_lock); at line 1475
function dlm_migrate_request_handler: (dlm->master_lock <- res->spinlock)
-------------------------------------------------------
spin_lock(&dlm->master_lock) at line 3036
spin_lock(&res->spinlock); at line 3039
