ocfs2: free 'dummy_sc' in sc_fop_release() to prevent memory leak

2017-07-06T23:24:30Z

'sd->dbg_sock' is malloced in sc_common_open(), but not freed at the end of sc_fop_release().

locking/atomic, kref: Add kref_read()

2017-01-14T10:37:18Z

Since we need to change the implementation, stop exposing internals. Provide kref_read() to read the current reference count; typically used for debug messages. Kills two anti-patterns: atomic_read(&kref->refcount) kref->refcount.counter Signed-off-by: Peter Zijlstra (Intel) Cc: Andrew Morton Cc: Greg Kroah-Hartman Cc: Linus Torvalds Cc: Paul E.

fs/ocfs2/cluster/netdebug.c: use seq_open_private() not seq_open()

2014-10-10T02:25:47Z

Reduce boilerplate code by using seq_open_private() instead of seq_open() Note that the code in and using sc_common_open() has been quite extensively changed. Not least because there was a latent memory leak in the code as was: if sc_common_open() failed, the previously allocated buffer was not freed.

ocfs2/cluster: Add new function o2net_fill_node_map()

2011-07-24T17:32:54Z

Patch adds function o2net_fill_node_map() to return the bitmap of nodes that it is connected to. This bitmap is also accessible by the user via the debugfs file, /sys/kernel/debug/o2net/connected_nodes. Signed-off-by: Sunil Mushran

ocfs2/cluster: dereferencing before checking in nst_seq_show()

2011-01-08T02:02:03Z

In the original code, we dereferenced "nst" before checking that it was non-NULL. I moved the check forward and pulled the code in an indent level. Signed-off-by: Dan Carpenter Signed-off-by: Joel Becker
