[RFC PATCH v4 01/17] vfs: export new_inode_pseudo

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Ceph needs to be able to allocate inodes ahead of a create that might
involve a fscrypt-encrypted inode. new_inode() almost fits the bill,
but it puts the inode on the sb->s_inodes list and when we go to hash
it, that might be done again.

We could work around that by setting I_CREATING on the new inode, but
that causes ilookup5 to return -ESTALE if something tries to find it
before I_NEW is cleared. To work around all of this, just use
new_inode_pseudo which doesn't add it to the list.
