So, IMHO, it can consume memory too much, since tfm should be allocated for every inodes and be alive until inode eviction.
Are you sure this is a real problem? Have you actually looked at how much memory it consumes?
Apart from giving GFP_NOFS, do you mean that it is a wrong approach?
Allocating the tfm and setting a key on the data path is not acceptable. Cheers, -- Email: Herbert Xu [off-list ref] Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
