new ->follow_link() and ->put_link() calling conventions 2015-05-11T02:19:45+00:00 Al Viro viro@zeniv.linux.org.uk 2015-05-02T17:32:22+00:00 680baacbca69d18a6d7315374ad83d05ac9c0977 a) instead of storing the symlink body (via nd_set_link()) and returning an opaque pointer later passed to ->put_link(), ->follow_link() _stores_ that opaque pointer (into void * passed by address by caller) and returns the symlink body. Returning ERR_PTR() on error, NULL on jump (procfs magic symlinks) and pointer to symlink body for normal symlinks. Stored pointer is ignored in all cases except the last one. Storing NULL for opaque pointer (or not storing it at all) means no call of ->put_link(). b) the body used to be passed to ->put_link() implicitly (via nameidata). Now only the opaque pointer is. In the cases when we used the symlink body to free stuff, ->follow_link() now should store it as opaque pointer in addition to returning it. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Storing NULL for opaque pointer (or not storing it at all) means no call
of ->put_link().

9p: don't bother with __getname() in ->follow_link() 2015-05-11T02:18:19+00:00 Al Viro viro@zeniv.linux.org.uk 2015-04-14T21:42:49+00:00 90e4fc8890daecea72ef73ac8047050e3e8d32db We copy there a kmalloc'ed string and proceed to kfree that string immediately after that. Easier to just feed that string to nd_set_link() and _not_ kfree it until ->put_link() (which becomes kfree_put_link() in that case). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
