.SH NOTES
|
||||
If these devices are not writable and readable for all users, many
|
||||
programs will act strangely.
|
||||
|
||||
Since Linux 2.6.31,
|
||||
.\" commit 2b83868723d090078ac0e2120e06a1cc94dbaef0
|
||||
reads from
|
||||
.IR /dev/zero
|
||||
are interruptible by signals.
|
||||
(This change was made to help with bad latencies for large reads from
|
||||
.IR /dev/zero .)
