This is a note to let you know that I've just added the patch titled
staging: r8188eu: use GFP_ATOMIC under spinlock
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: r8188eu: use GFP_ATOMIC under spinlock
In function rtw_report_sec_ie() kzalloc() is called under a spinlock,
so the allocation have to be atomic.
Call tree:
-> rtw_select_and_join_from_scanned_queue() <- takes a spinlock
-> rtw_joinbss_cmd()
-> rtw_restruct_sec_ie()
-> rtw_report_sec_ie()
