Just tested the patch and it works here, but wouldn't it be better to
add a "waiting" flag to the mode display, or something like that?
("WAIT-READ" and "WAIT-WRITE"?)



Side note: It seems that fs/locks.c:lock_get_status can output many
other variations – e.g. mandatory locks have a third type called
"ACCESS", shown when a program tries to simply read/write a locked file;
in this case listing the R/W mode might be more useful than "WAITING".
Mandatory locks can apparently say "RW" as well, although I haven't
found a way to create a "RW" lock yet.

Also, while I haven't yet seen this in practice either, the same
fs/locks.c can output lock type "LEASE", which has completely different
values for the 3rd field, and cannot be represented by a binary
"M[andatory] = 0/1" column.
