ash: exec: Do not allocate stack string in padvance
Upstream commit: Date: Sat, 19 May 2018 02:39:48 +0800 exec: Do not allocate stack string in padvance Many callers of padvance immediately free the allocated string so this patch moves the stalloc call to the caller. Instead of returning the allocated string, padvance now returns the length to allocate (this may be longer than the actual string length, even including the NUL). For the case where we would previously return NULL, we now return -1. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
