linux-next: manual merge of the vfs tree with the ext4 tree

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

 



Hi Al,

Today's linux-next merge of the vfs tree got a conflict in
fs/ext4/symlink.c between commit b7236e21d55f ("ext4 crypto: reorganize
how we store keys in the inode") from the ext4 tree and commit
680baacbca69 ("new ->follow_link() and ->put_link() calling
conventions") from the vfs tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
