On architectures that use a signed char type by default, this results in an invalid date for anything beyond 2027. This changes the function argument to a 'u8' array, which is defined the same way on all architectures, and unambiguously lets us use years until 2155.

Fix child-node lookup during initialisation, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent gic node was prematurely freed, while the ppi-partitions node was leaked.

[Linux-stable-mirror] Patch "ext4: fix interaction between i_size, fallocate, and delalloc after a crash" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ext4: fix interaction between i_size, fallocate, and delalloc after a crash to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: ext4-fix-interaction-between-i_size-fallocate-and-delalloc-after-a-crash.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 51e3ae81ec58e95f10a98ef3dd6d7bce5d8e35a2 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o <tytso(a)mit.edu> Date: Fri, 6 Oct 2017 23:09:55 -0400 Subject: ext4: fix interaction between i_size, fallocate, and delalloc after a crash From: Theodore Ts'o <tytso(a)mit.edu> commit 51e3ae81ec58e95f10a98ef3dd6d7bce5d8e35a2 upstream. If there are pending writes subject to delayed allocation, then i_size will show size after the writes have completed, while i_disksize contains the value of i_size on the disk (since the writes have not been persisted to disk). If fallocate(2) is called with the FALLOC_FL_KEEP_SIZE flag, either with or without the FALLOC_FL_ZERO_RANGE flag set, and the new size after the fallocate(2) is between i_size and i_disksize, then after a crash, if a journal commit has resulted in the changes made by the fallocate() call to be persisted after a crash, but the delayed allocation write has not resolved itself, i_size would not be updated, and this would cause the following e2fsck complaint: Inode 12, end of extent exceeds allowed value (logical block 33, physical block 33441, len 7) This can only take place on a sparse file, where the fallocate(2) call is allocating blocks in a range which is before a pending delayed allocation write which is extending i_size. Since this situation is quite rare, and the window in which the crash must take place is typically < 30 seconds, in practice this condition will rarely happen. Nevertheless, it can be triggered in testing, and in particular by xfstests generic/456.
