ocfs2: export ocfs2_kset for online file check
When there are errors in the ocfs2 filesystem, they are usually
accompanied by the inode number which caused the error. This inode
number would be the input to fixing the file. One of these options
could be considered:
A file in the sys filesytem which would accept inode numbers. This
could be used to communication back what has to be fixed or is fixed.
You could write:
$# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/check
or
$# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/fix
Compare with second version, I re-design filecheck sysfs interfaces,
there are three sysfs files (check, fix and set) under filecheck
directory (see above), sysfs will accept only one argument <inode>.
Second, I adjust some code in ocfs2_filecheck_repair_inode_block()
function according to upstream feedback, we cannot just add VALID_FL
flag back as a inode block fix, then we will not fix this field
corruption currently until having a complete solution. Compare with
first version, I use strncasecmp instead of double strncmp functions.
Second, update the source file contribution vendor.
This patch (of 4):
Export ocfs2_kset object from ocfs2_stackglue kernel module, then online
file check code will create the related sysfiles under ocfs2_kset
object. We're exporting this because it's built in ocfs2_stackglue.ko.
