initramfs_test: kunit tests for initramfs unpacking Provide some basic initramfs unpack sanity tests covering: - simple file / dir extraction - filename field overrun, as reported and fixed separately via https://lore.kernel.org/r/20241030035509.20194-2-ddiss@suse.de - "070702" cpio data checksums - hardlinks Signed-off-by: David Disseldorp <ddiss@suse.de> Link: https://lore.kernel.org/r/20250304061020.9815-3-ddiss@suse.de Signed-off-by: Christian Brauner <brauner@kernel.org>

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
