We had a few drivers move from arch/arm into drivers/gpio, but they don't actually compile without the ARM platform headers etc. As a result they were messing up allyesconfig on x86.

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. Signed-off-by: NTyler Hicks <tyhicks@linux.vnet.ibm.com>

ecryptfs_lookup_interpose() has turned into spaghetti code over the years. This is an effort to clean it up. - Shorten overly descriptive variable names such as ecryptfs_dentry - Simplify gotos and error paths - Create helper function for reading plaintext i_size from metadata It also includes an optimization when reading i_size from the metadata. A complete page-sized kmem_cache_alloc() was being done to read in 16 bytes of metadata. The buffer for that is now statically declared. Signed-off-by: NTyler Hicks <tyhicks@linux.vnet.ibm.com>

Instead of having the calling functions translate the true/false return code to either 0 or -EINVAL, have contains_ecryptfs_marker() return 0 or -EINVAL so that the calling functions can just reuse the return code. Also, rename the function to ecryptfs_validate_marker() to avoid callers mistakenly thinking that it returns true/false codes. Signed-off-by: NTyler Hicks <tyhicks@linux.vnet.ibm.com>

An io_state pre-allocates an error information structure for each possible osd-device that might error during IO. When IO is done if all was well the io_state is freed. (as today). If the I/O has ended with an error, the io_state is queued on a per-layout err_list. When eventually encode_layoutreturn() is called, each error is properly encoded on the XDR buffer and only then the io_state is removed from err_list and de-allocated. It is up to the io_engine to fill in the segment that fault and the type of osd_error that occurred. By calling objlayout_io_set_result() for each failing device.

A pNFS client auto-negotiates a lot of features (minorversion level, pNFS layout type, etc.). This is convenient, but makes certain kinds of failures hard for a user to detect. For example, if the client falls back on 4.0, or falls back to MDS IO because the user didn't connect to the right iscsi disks before mounting, the only symptoms may be reduced performance, which may not be noticed till long after the actual failure, and may be difficult for a user to diagnose. However, such "failures" may also be perfectly normal in some cases, so we don't want to spam the system logs with them. One approach would be to put some more information into /proc/self/mountstats.
