[ Upstream commitacac75bb45] 'rtl8192_irq_rx_tasklet()' is a tasklet initialized in 'rtl8192_init_priv_task()'. >From this function it is possible to allocate some memory with the GFP_KERNEL flag, which is not allowed in the atomic context of a tasklet. Use GFP_ATOMIC instead. The call chain is: rtl8192_irq_rx_tasklet (in r8192U_core.c) --> rtl8192_rx_nomal (in r8192U_core.c) --> ieee80211_rx (in ieee80211/ieee80211_rx.c) --> RxReorderIndicatePacket (in ieee80211/ieee80211_rx.c) Fixes:79a5ccd972("staging: rtl8192u: fix large frame size compiler warning") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/20200813173458.758284-1-christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
