2015-05-31ext4 crypto: shrink size of the ext4_crypto_ctx structureTheodore Ts'o1-5/+5
Some fields are only used when the crypto_ctx is being used on the read path, some are only used on the write path, and some are only used when the structure is on free list. Optimize memory use by using a union. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

2015-04-08ext4 crypto: add ext4_mpage_readpages()Theodore Ts'o1-0/+264
This takes code from fs/mpage.c and optimizes it for ext4. Its primary reason is to allow us to more easily add encryption to ext4's read path in an efficient manner. Signed-off-by: Theodore Ts'o <tytso@mit.edu>
