  "message": "jbd2: add the b_cow_tid field to journal_head struct\n\nThe b_cow_tid field will be used by the ext4 snapshots code to store\nthe transaction id when the buffer was last cowed.\n\nMerging this patch to mainline will allow users to test ext4 snapshots\nas a standalone module, without the need to patch and install a\ndevelopment kernel.\n\nOn 64bit machines this field uses fills in a padding \"hole\" and does\nnot increase the size of the struct.  On a 32bit machine this patch\nincreases the size of the struct from 60 to 64 bytes.\n\nSigned-off-by: Amir Goldstein \u003camir73il@users.sf.net\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n",
