      "message": "ext4: Fix BUG when writing to an unitialized extent\n\nThis patch fixes a bug when writing to preallocated but uninitialized\nblocks, which resulted in a BUG in fs/buffer.c saying that the buffer\nis not mapped.\n\nWhen writing to a file, ext4_get_block_wrap() is called with create\u003d1 in\norder to request that blocks be allocated if necessary.  It currently\ncalls ext4_get_blocks() with create\u003d0 in order to do a lookup first.  If\nthe inode contains an unitialized data block, the buffer head is left\nunampped, which ext4_get_blocks_wrap() returns, causing the BUG.\n\nWe fix this by checking to see if the buffer head is unmapped, and if\nso, we make sure the the buffer head is mapped by calling\next4_ext_get_blocks with create\u003d1.\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n"

Thus\nthe compile warning occurs.\n\nThought about changing the jbd2_journal_enable_debug data type back to\nint, but can\u0027t, because the jbd2-debug is moved to debug fs, where\ncalling debugfs_create_u8() to create the debugfs entry needs the value\nto be u8 type.\n\nEven if we changed the data type back to int, the code is still buggy,\nkernel should not print jbd2 debug message if the\njbd2_journal_enable_debug is set to 0. But this is not the case.\n\nThe fix is change the level of debugging to 1.

We use\ns_want_extra_isize and s_min_extra_isize to decide by how much we should\nexpand the inode. If EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature is set\nthen we expand the inode by max(s_want_extra_isize, s_min_extra_isize ,\nsizeof(ext4_inode) - EXT4_GOOD_OLD_INODE_SIZE) bytes. Actually it is\nstill an open question about whether users should be able to set\ns_*_extra_isize smaller than the known fields or not.\n\nThis patch also adds the functionality to expand inodes to include the\nnewly added fields. We start by trying to expand by s_want_extra_isize\nbytes and if its fails we try to expand by s_min_extra_isize bytes. This\nis done by changing the i_extra_isize if enough space is available in\nthe inode and no EAs are present. If EAs are present and there is enough\nspace in the inode then the EAs in the inode are shifted to make space.\nIf enough space is not available in the inode due to the EAs then 1 or\nmore EAs are shifted to the external EA block. In the worst case when\neven the external EA block does not have enough space we inform the user\nthat some EA would need to be deleted or s_min_extra_isize would have to\nbe reduced.\n\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Kalpak Shah \u003ckalpak@clusterfs.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n"
