Re: [U-Boot] [PATCH] malloc: Fix issue with calloc memory possibly being non-zero

Dear Kumar Gala,

In message 1289854274-7006-1-git-send-email-galak@kernel.crashing.org you wrote:

Since we set #define MORECORE_CLEARS 1, the code assumes 'sbrk' always returns zero'd out memory. However since its possible that free() returns memory ack to sbrk() via malloc_trim we could possible get non-zero'd memory from sbrk() if it allocates back memory that was previously freed to it.

I confirm that the test case works fine here, too. So:

Tested-by: Wolfgang Denk wd@denx.de

But the commit message needs serious rework before this can get applied.

Best regards,
