Hi, I am seeing in the ext4_change_inode_flag() function and found a patch to allocate physical blocks for delalloc blocks in that function. (=> http://repo.or.cz/w/ext4-patch-queue.git/blob/20f7782b1f50eb1d5cba5e085d01fbce89fce881:/allocate-delalloc-blocks-before-changing-journal-mode) I think this is an idea to resolve kernel OOPS concerned with enabling/disabling data journaling of a file in delayed allocation mode. Actually, I want to utilize per file data journaling with delayed allocation, so this patch seemed to be very helpful for me. But, after 1 month from when the patch was applied, another patch was submitted and EXT4_INODE_JOURNAL_DATA flag with delalloc was ignored. (=> http://repo.or.cz/w/ext4-patch-queue.git/blob/17f3a9c17473d0b5925118a75ba7363c79e3fdc3:/ignore-JOURNAL_DATA-flag-with-delalloc) I don't understand the reason of that EXT4_INODE_JOURNAL_DATA flag with delalloc was ignored because I think the previous patch can handle the problem which the above URL describes. Am I missing something and could you share your idea about this? :-) ��.n��������+%������w��{.n�����{�����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
