Re: 2.4.13 memory leaks
it is entirely possible that the leaks are specific to 2.4.13 or to my kernel config...but just the same there shouldnt be a leak at all, just felt like warning anyone with similar setups as mine...
(i only installed the 2.4.13 kernel at the time because it was the only 2.4 kernel patch i could find for ext3, and i need 2.4 for a number of reasons)

at the time of this posting 2.4.16 is the current
kernel and ext3 is in the kernel src now without
a patch. I haven't heard of massive mem leaks
with the -current. I know people have their
various reasons for running old kernels but 2.4.13
wouldn't seem like a popular choice even so.
2.4.13 memory leaks
havnt had the time to track down the exact part of the code, but (at least on my configuration) there is a huge memory leak, it takes about 8k per second...same config minus the patch and no leak, im fairly sure this is a problem with this patch...
if you're using this patch just watch out...ill see if i cant track down this bug when i get some time....
ext3 patches for 2.4
Seems they're now located at:
http://www.zipworld.com.au/~akpm/linux/ext3/
ext3 merged into -ac kernels
Alan Cox's kernel tree now contains integrated ext3, as of linux-2.4.7-ac4.
