Subjectlinux-next: build failure after merge of the staging-next tree
Hi Greg,

After merging the staging-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/md/md.c: In function 'level_store':
drivers/md/md.c:3029: error: too few arguments to function 'sysfs_get_dirent'

Caused by commit 262f8e4937e7b4a587923ca3c039a184668f49ec ("sysfs:
Implement sysfs tagged directory support") from the driver-core tree
interacting with commit fecc531e3cc0de60514d326c7d82f1075ed55888 ("md:
manage redundancy group in sysfs when changing level") from the md.

I have applied this fixup patch for today and can carry it as necessary.

[This could have been avoided, of course, by creating a new API (maybe
sysfs_get_dirent_tagged) and implementing the old API in terms of that].
