expr treats all numbers as decimals, so prepending a zero is safe. Note that the KERNEL_VERSION() macro still takes three arguments, 3.0 has to be written as KERNEL_VERSION(3,0,0). Signed-off-by:

.. except there are various scripts that really know that there are three numbers, so it calls itself "3.0.0-rc1". Hopefully by the time the final 3.0 is out, we'll have that extra zero all figured out. Signed-off-by:

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. Make them depend on ARM. Reported-by:

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:

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:

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:

Only unlock and d_add() new inodes after the plaintext inode size has been read from the lower filesystem. This fixes a race condition that was sometimes seen during a multi-job kernel build in an eCryptfs mount. https://bugzilla.kernel.org/show_bug.cgi?id=36002Signed-off-by:

By default, unless pnfs is used coalesce pages until pg_bsize (rsize or wsize) is reached. pnfs layout drivers define their own pg_test methods that use pnfs_generic_pg_test and need to define their own I/O size limits (e.g. based on the file stripe size).

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. In objio_osd: * Allocate io-error descriptors space as part of io_state * Use generic objlayout error reporting at end of io. Signed-off-by:

With the objects layout security model, we have object capabilities that are associated with the layout and we anticipate that the server will issue a cb_layoutrecall for any setattr that changes security related attributes (user/group/mode/acl) or truncates the file.

Support for stripping over mirrors with a received stripe_unit. There are however a few constrains which are not supported: 1. Stripe Unit must be a multiple of PAGE_SIZE 2. stripe length (stripe_unit * number_of_stripes) can not be bigger then 32bit. Also support raid-groups and partial-layout. Partial-layout is when not all the groups are received on the line, addressing only a partial range of the file.
