main_proc_lock and int_lock (in mwifiex_adapter) are the only spinlocks
used in hardirq contexts. The rest are only in task or softirq contexts.
Convert every other lock from *_irq{save,restore}() variants to _bh()
variants.
This is a mechanical transformation of all spinlock usage in mwifiex
using the following:
Step 1:
I ran this nasty sed script:
sed -i -E '/spin_lock_irqsave|spin_unlock_irqrestore/ {
/main_proc_lock|int_lock/! {
s:(spin_(un|)lock)_irq(save|restore):\1_bh: ;
# Join broken lines.
:a /;$/! {
N;
s/\s*\n\s*//;
ba
}
/,.*\);$/ s:,.*\):\):
}
}' drivers/net/wireless/marvell/mwifiex/*
Step 2:
Apply this semantic patch (coccinelle) to remove the unused 'flags'
variables:
// <smpl>
@@
type T;
identifier i;
@@
(
extern T i;
|
- T i;
... when != i
)
// </smpl>
Testing: I've played with a variety of stress tests, including download
stress tests on the same APs which caught regressions with commit
5188d5453bc9 ("mwifiex: restructure rx_reorder_tbl_lock usage"). I've
primarily tested on Marvell 8997 / PCIe, although I've given 8897 / SDIO
a quick spin as well.
