    vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
    Linus Torvalds authored
    This is the mindless scripted replacement of kernel use of POLL*
    variables as described by Al, done by this script:
    
        for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
            L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
            for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
        done
    
    with de-mangling cleanups yet to come.
    
    NOTE! On almost all architectures, the EPOLL* constants have the same
    values as the POLL* constants do.  But they keyword here is "almost".
    For various bad reasons they aren't the same, and epoll() doesn't
    actually work quite correctly in some cases due to this on Sparc et al.
    
    The next patch from Al will sort out the final differences, and we
    should be all done.
