Hello, Our static analysis tool finds some possible data races in the OCFS2 file system in Linux 6.4.0-rc6. In most calling contexts, the variables such as res->lockname.name and res->owner are accessed with holding the lock res->spinlock. Here is an example: lockres_seq_start() --> Line 539 in dlmdebug.c spin_lock(&res->spinlock); --> Line 574 in dlmdebug.c (Lock res->spinlock) dump_lockres(res, ...); --> Line 575 in fs/ocfs2/dlm/dlmdebug.c stringify_lockname(res->lockname.name, ...); --> Line 493 in dlmdebug.c (Access res->loc...

Found 15 patches (out of 162) that appeared relevant to ocfs2 1.4. Please review. Sunil

The following series of patches comprises the bulk of our outstanding changes for Ocfs2.
