Subject: [Linux-ia64] Possible bug in getname32
Date: Fri, 16 Mar 2001 16:04:23 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590693005284@msgid-missing> (raw)
Although I do not work on linux-ia64, I believe we found a bug bringing up
PPC64 that also exists in the IA64 code that someone might want to look
into.
In arch/ia64/ia32/sys_ia32.c, the function getname32 allocates storage via
__get_free_page and then returns it via putname (aka kmem_cache_free).
This mismatch of storage allocation schemes can cause all kinds of subtle
problems as we found in PPC64.
Is this a legitimate bug, or are we missing something here?
Thanks -
