Subject: [patch 0/7] Asynchronous Notification for ATAPI devices (v2) -
resend
This patch series implements Asynchronous Notification (AN) for SATA
ATAPI devices as defined in SATA 2.5 and AHCI 1.1 and higher. Drives
which support this feature will send a notification when new media is
inserted and removed, preventing the need for user space to poll for
new media. This support is exposed to user space via a flag that will
be set in /sys/block/sr*/capability_flags. If the flag is set, user
space can disable polling for the new media, and the genhd driver will
send a KOBJ_CHANGE event with the envp set to MEDIA_CHANGE_EVENT=1.
Note that this patch only implements support for directly attached
drives - AN with drives attached to a port multiplier requires
additional changes.
Thanks!
Kristen
