target: add a new add_wwn_groups fabrics method

2016-03-31T03:06:44+00:00

We need to have the WWN fully initialized before addig default groups to it,
so add a new method to add these groups after the WWN has been initialized.
Also remove the default groups in the core while we're at it.

2016-03-17T23:25:46+00:00

Pull configfs updates from Christoph Hellwig:

 - A large patch from me to simplify setting up the list of default
   groups by actually implementing it as a list instead of an array.

 - a small Y2083 prep patch from Deepa Dinamani.  Probably doesn't
   matter on it's own, but it seems like he is trying to get rid of all
   CURRENT_TIME uses in file systems, which is a worthwhile goal.

target: Remove enum transport_lunflags_table

2016-03-11T05:48:55+00:00

se_dev_entry.lun_flags and se_lun.lun_access are only used for keeping
track of read-write vs. read-only state. Since this is an either/or thing
we can represent it as bool, and remove the unneeded enum
transport_lunflags_table, which is left over from when there were more
flags.

Change code that uses this enum to just use true/false, and make it clear
through variable and param names that true means read-only, false means
read-write.

configfs: switch ->default groups to a linked list

2016-03-06T15:11:24+00:00

Replace the current NULL-terminated array of default groups with a linked
list.  This gets rid of lots of nasty code to size and/or dynamically
allocate the array.

While we're at it also provide a conveniant helper to remove the default
groups.

Based on HCH's original patch, this adds a full version to
support percpu-ida tag pre-allocation and callback function
pointer into fabric driver code to complete session setup.
