[PATCH 1/3] staging: lustre: Convert return seq_printf(...) uses to seq_has_overflowed

From: Joe Perches
Date: Mon Feb 16 2015 - 14:26:54 EST

The seq_printf return value will eventually be converted to void.

Convert these uses to:

seq_printf(seq, ...);
return seq_has_overflowed(seq);

Done via cocci script:

@@
struct seq_file *seq;
@@

- return
\(seq_printf\|seq_puts\|seq_putc\)(seq,
...);

+ return seq_has_overflowed(seq);

With some additional reformatting and typing post conversion

Miscellanea:

o convert an rc++ use to a bool
o use seq_puts with fixed strings where appropriate
