fcntl.2: Mention that l_sysid is not used even if present
...
Some architectures do provide an 'l_sysid' declaration in
struct flock; however, it is not used anyway.
* man2/fcntl.2 (.SH NOTES): Note that l_sysid field is not used on
Linux even if present on some architectures.

fcntl.2: Actual pipe capacity may in practice be less than nominal capacity
...
The number of bytes that can be written to the pipe may be less
(sometimes substantially less) than the nominal capacity. This
was confirmed with some testing. For example, when writing
4097-byte blocks to a pipe with 65536 byte capacity, only 45066
bytes could be written (i.e., 20470 bytes less than 65536).

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;
