* cxgb3: Don't call cxgb_vlan_mode until q locks are initializedRoland Dreier2012-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver calls cxgb_vlan_mode() from init_one(). This calls into synchronize_rx(), which locks all the q locks, but the q locks are not initialized until cxgb_up() -> setup_sge_qsets(). So move the call to cxgb_vlan_mode() into cxgb_up(), after the call to setup_sge_qsets(). We also move the body of these functions up higher to avoid having to a forward declaration. This was found because of the lockdep warning: INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

* simple_open: automatically convert to simple_open()Stephen Boyd2012-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.
