Hi,

With v3.13-rc3 I have an error when the atmel-mci driver calls
flush_dcache_page (log at the end of the message).

Since I didn't have it before, I did a git bisect and the commit introducing
the error is the following one:

106a74e slab: replace free and inuse in struct slab with newly introduced active

I don't know if this commit has introduced a bug or if it has revealed a bug
in the atmel-mci driver.

Hello,

I think that this commit may not introduce a bug. This patch remove one
variable on slab management structure and replace variable name. So there
is no functional change.

If I have reverted this patch and other ones you did on top of it and
the issue disappear.

Hello,

Could you give me your '/proc/slabinfo' before/after this commit (106a74e)?

And how about testing with artificially increasing size of struct slab on
top of this commit (106a74e)?

I really wonder why the problem happens, because this doesn't cause any
functional change as far as I know. Only side-effect from this patch is
decreasing size of struct slab.

Sorry I am not at the office, I have tried to reproduce it with a
different device and a different sdcard but without success. I'll test
it on Monday.

I am still not at the office but I get the same device and the same
sdcard and I don't reproduce it. I am not totally in the same
conditions. It seems there is an extra parameter causing this bug but I
don't figure out which one at the moment.

Okay. I will wait for you!

Thanks for informing progress.
