Subject: coccinelle: misc: secs_to_jiffies: Patch expressions too
Date: Tue, 25 Feb 2025 20:17:15 +0000
Patch series "Converge on using secs_to_jiffies() part two", v3.
This is the second series that converts users of msecs_to_jiffies() that
either use the multiply pattern of either of:
- msecs_to_jiffies(N*1000) or
- msecs_to_jiffies(N*MSEC_PER_SEC)
where N is a constant or an expression, to avoid the multiplication.
The conversion is made with Coccinelle with the secs_to_jiffies() script
in scripts/coccinelle/misc. Attention is paid to what the best change can
be rather than restricting to what the tool provides.
This patch (of 16):
Teach the script to suggest conversions for timeout patterns where the
arguments to msecs_to_jiffies() are expressions as well.
