NeilBrown 200724a707 SUNRPC/cache: fix reporting of expired cache entries in 'content' file. ... Entries that are in a sunrpc cache but are not valid should be reported with a leading '#' so they look like a comment. Commit d202cce896 (sunrpc: never return expired entries in sunrpc_cache_lookup) broke this for expired entries. This particularly applies to entries that have been replaced by newer entries. sunrpc_cache_update sets the expiry of the replaced entry to '0', but it remains in the cache until the next 'cache_clean'. The result is that if you echo 0 2000000000 1 0 > /proc/net/rpc/auth.unix.gid/channel several times, then cat /proc/net/rpc/auth.unix.gid/content It will display multiple entries for the one uid, which is at least confusing: #uid cnt: gids... 0 1: 0 0 1: 0 0 1: 0 With this patch, expired entries are marked as comments so you get #uid cnt: gids... 0 1: 0 # 0 1: 0 # 0 1: 0 These expired entries will never be seen by cache_check() as they are always *after* a non-expired entry with the same key - so the extra check is only needed in c_show() Signed-off-by: NeilBrown <neilb@suse.de> -- It's not a big problem, but it had me confused for a while, so it could well confuse others.
