Theodore Ts'o	614def7013	ext4 crypto: shrink size of the ext4_crypto_ctx structure ... 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>	2015-05-31 13:31:34 -04:00

Theodore Ts'o	f64e02fe9b	ext4 crypto: add ext4_mpage_readpages() ... 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>	2015-04-08 00:00:32 -04:00
