| H A D | file.c | 57ca7deb Tue Aug 04 06:11:47 CDT 2009 Anders Grafström <grfstrm@users.sourceforge.net> jffs2: Fix return value from jffs2_do_readpage_nolock()
This fixes "kernel BUG at fs/jffs2/file.c:251!".
This pseudocode hopefully illustrates the scenario that triggers it:
jffs2_write_begin {
jffs2_do_readpage_nolock {
jffs2_read_inode_range {
jffs2_read_dnode {
Data CRC 33c102e9 != calculated CRC 0ef77e7b for node at 005d42e4
return -EIO;
}
}
ClearPageUptodate(pg);
return 0;
}
}
jffs2_write_end {
BUG_ON(!PageUptodate(pg));
}
