[PATCH] r/o bind mount prepwork: move open_namei()'s vfs_create()
The code around vfs_create() in open_namei() is getting a bit too complex.
Right now, there is at least the reference count on the dentry, and the
i_mutex to worry about. Soon, we'll also have mnt_writecount.
So, break the vfs_create() call out of open_namei(), and into a helper
function. This duplicates the call to may_open(), but that isn't such a bad
thing since the arguments (acc_mode and flag) were being heavily massaged
anyway.
