Subject: __you_cannot_kmalloc_that_much
Date: Thu, 19 Jun 2003 18:33:59 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105604765306485@msgid-missing> (raw)
While trying to compile the latest pull from
the lia64.bkbits.net:8080/linux-ia64-2.5
repository I hit the "you_cannot_kmalloc_that_much"
message in the final link.
The culprit is in
drivers/usb/host/uhci-debug.c
which contains:
#define MAX_OUTPUT (PAGE_SIZE * 16)
...
up->data = kmalloc(MAX_OUTPUT, GFP_KERNEL);
With the default 16k page size we are trying to
allocate 256K of memory, which is bigger that the
largest size pool in include/linux/kmalloc_sizes.h
Do we need a larger pool (I don't think so) or is
this allocation excessive?
