Just a minor (or major) doubt.
The function returns GRU_NUM_TFM * GRU_CACHE_LINE_BYTES and the for loop
is also running till GRU_NUM_TFM so I am assuming that the function can
handle buffer till size of GRU_NUM_TFM * GRU_CACHE_LINE_BYTES. So the
error -EFBIG should occur when the buffer is more than this. Then
shouldn't it be:
if ((GRU_NUM_TFM * GRU_CACHE_LINE_BYTES) < (ubufend - ubuf))
return -EFBIG;
or i am wrong in interpreting it?
regards
sudip
