[Crash-utility] [PATCH] Fix for swap used percentage reporting when totalswap_pages is 0.

Without the patch, when totalswap_pages is 0, swap used percentage reports as 100%. This is confusing on first glance as it seems to indicate potential memory pressure. Fix this and also fix indentation on 'pct' calculations to improve readability. --- memory.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/memory.c b/memory.c index e994d13..f39c667 100644 --- a/memory.c +++ b/memory.c @@ -8302,12 +8302,12 @@ dump_kmeminfo(void) fprintf(fp, "%13s %7ld %11s ----\n", "TOTAL SWAP", totalswap_pages, pages_to_size(totalswap_pages, buf)); - pct = totalswap_pages ?
