It can take some time to validate the image, make sure {allyes|allmod}config doesn't enable it. I'd say randconfig will cover it often enough, and the failure is also borderline build coverage related: you cannot really make the decoder test fail via source level changes, only with changes in the build environment, so I agree with Andi that we can disable this one too.

This changes 'do_execve()' to get the executable name as a 'struct filename', and to free it when it is done. This is what the normal users want, and it simplifies and streamlines their error handling. The controlled lifetime of the executable name also fixes a use-after-free problem with the trace_sched_process_exec tracepoint: the lifetime of the passed-in string for kernel users was not at all obvious, and the user-mode helper code used UMH_WAIT_EXEC to serialize the pathname allocation lifetime with the execve() having finished, which in turn meant that the trace point that happened after mm_release() of the old process VM ended up using already free'd memory. To solve the kernel string lifetime issue, this simply introduces "getname_kernel()" that works like the normal user-space getname() function, except with the source coming from kernel memory. As Oleg points out, this also means that we could drop the tcomm[] array from 'struct linux_binprm', since the pathname lifetime now covers setup_new_exec(). That would be a separate cleanup.

It really isn't very interesting to have DEBUG_INFO when doing compile coverage stuff (you wouldn't want to run the result anyway, that's kind of the whole point of COMPILE_TEST), and it currently makes the build take longer and use much more disk space for "all{yes,mod}config". There's somewhat active discussion about this still, and we might end up with some new config option for things like this (Andi points out that the silly X86_DECODER_SELFTEST option also slows down the normal coverage tests hugely), but I'm starting the ball rolling with this simple one-liner. DEBUG_INFO isn't that noticeable if you have tons of memory and a good IO subsystem, but it hurts you a lot if you don't - for very little upside for the common use.

posix_acl_xattr_get requires get_acl() to return EOPNOTSUPP if the filesystem cannot support acls. This is needed for NFS, which can't know whether or not the server supports acls until it tries to get/set one.

It seems that when init_btrfs_fs() is called, crc32c/crc32c-intel might not always be already initialized, which results in the call to crypto_alloc_shash() returning -ENOENT, as experienced by Ahmet who reported this. Therefore make sure init_btrfs_fs() is called after crc32c is initialized (which is at initialization level 6, module_init), by using late_initcall (which is at initialization level 7) instead of module_init for btrfs.

This made it not possible to build a kernel with btrfs enabled (either as module or built-in) if libcrc32c is not enabled as well.

HPFS needs to load 4 consecutive 512-byte sectors when accessing the directory nodes or bitmaps. We can't switch to 2048-byte block size because files are allocated in the units of 512-byte sectors. Previously, the driver would allocate a 2048-byte area using kmalloc, copy the data from four buffers to this area and eventually copy them back if they were modified. In the current implementation of the buffer cache, buffers are allocated in the pagecache. That means that 4 consecutive 512-byte buffers are stored in consecutive areas in the kernel address space. So, we don't need to allocate extra memory and copy the content of the buffers there. This patch optimizes the code to avoid copying the buffers. It checks if the four buffers are stored in contiguous memory - if they are not, it falls back to allocating a 2048-byte area and copying data there.

Previously, hpfs scanned all bitmaps each time the user asked for free space using statfs. This patch changes it so that hpfs scans the bitmaps only once, remembes the free space and on next invocation of statfs it returns the value instantly. New versions of wine are hammering on the statfs syscall very heavily, making some games unplayable when they're stored on hpfs, with load times in minutes. This should be backported to the stable kernels because it fixes user-visible problem (excessive level load times in wine).
