Subject: eCryptfs: Remove ecryptfs_header_cache_2
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3063287053bca5207e121c567b95b2b6f0bdc2c8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

eCryptfs: Remove ecryptfs_header_cache_2

Now that ecryptfs_lookup_interpose() is no longer using
ecryptfs_header_cache_2 to read in metadata, the kmem_cache can be
removed and the ecryptfs_header_cache_1 kmem_cache can be renamed to
ecryptfs_header_cache.
