From: Eric Biggers <redacted> Add a root-only variant of the FS_IOC_REMOVE_ENCRYPTION_KEY ioctl which removes all users' claims of the key, not just the current user's claim. I.e., it always removes the key itself, no matter how many users have added it. This is useful for forcing a directory to be locked, without having to figure out which user ID(s) the key was added under. This is planned to be used by a command like 'sudo fscrypt lock DIR --all-users' in the fscrypt userspace tool (http://github.com/google/fscrypt). Signed-off-by: Eric Biggers <redacted>
Looks good, thanks. Feel free to add: Reviewed-by: Theodore Ts'o <tytso@mit.edu> ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
