Michael Kerrisk acf0d7db21 fcntl.2: File seals are not generally applicable to tmpfs(5) files
As far as I can see, file seals can be applied only to
memfd_create(2) file descriptors. This was checked by experiment
and by reading mm/shmem.c::shmem_get_inode((), where one finds
the following line that applies to all new shmem files:

                info->seals = F_SEAL_SEAL;

Only in the code of the memfd_create() system call is this
setting reversed (in mm/shmem.c::memfd_create):

        if (flags & MFD_ALLOW_SEALING)
                info->seals &= ~F_SEAL_SEAL;

Michael Kerrisk 7255c7c0df fcntl.2: Rework description of F_SETOWN

requires the use of both F_SETOWN and O_ASYNC. While we're at,
make a few other cleanups to the text.
