EDAC: Use edac_debugfs_remove_recursive() in edac_debugfs_exit()

2016-02-10T09:37:46Z

debugfs_remove() is used to remove a file or a directory from the debugfs filesystem on an EDAC device exit. However edac_debugfs might not be empty. This is similar to 30f84a891bf6 ("EDAC: Use edac_debugfs_remove_recursive()") which changed the EDAC MCI code to use edac_debugfs_remove_recursive().

EDAC: Use edac_debugfs_remove_recursive()

2015-10-14T16:50:32Z

debugfs_remove() is used to remove a file or a directory from the debugfs filesystem, but mci->debugfs might not empty. This can be triggered by the following sequence: 1) Enable CONFIG_EDAC_DEBUG 2) insmod an EDAC module (like i3000_edac or similar) 3) rmmod this module 4) we can see files remaining under /edac/ like "fake_inject", for example. Removing edac_core then, causes a NULL pointer dereference.

EDAC: Carve out debugfs functionality

2015-09-22T10:29:46Z

... into a separate compilation unit and drop a couple of CONFIG_EDAC_DEBUG ifdefferies. Rename edac_create_debug_nodes() to edac_create_debugfs_nodes(), while at it. No functionality change. Cc: Signed-off-by: Borislav Petkov
