Hello,
Some places in the code uses variable-size allocation on stack.. For example from hmac_setkey():
struct { struct shash_desc shash; char ctx[crypto_shash_descsize(hash)]; } desc;
sparse complains
CHECK crypto/hmac.c crypto/hmac.c:57:47: error: bad constant expression
I like it instead of kmalloc..
But what is position of kernel community about it?
