Package: util-linux
Version: 2.41-5devuan1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

* What led up to the situation?

running the command:

ls -t|more

on an EXFAT filesystem

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

ran

ls -t|strace more

and saw repeated output of the form:
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}, {fd=0, events=POLLIN|POLLERR|POLLHUP}, {fd=2, events=POLLIN|POLLERR|POLLHUP}], 3, -1) = 1 ([{fd=0, revents=POLLIN}])

on an ext3 filesystem, the same command does not show repeated output
and pauses after the following output:

poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}, {fd=0, events=POLLIN|POLLERR|POLLHUP}, {fd=2, events=POLLIN|POLLERR|POLLHUP}], 3, -1) = 1 ([{fd=0, revents=POLLIN|POLLHUP}])
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}, {fd=-1}, {fd=2, events=POLLIN|POLLERR|POLLHUP}], 3, -1



* What was the outcome of this action?
* What outcome did you expect instead?

ls -t|more

should not go into a busy loop
