This MR adds fixes for several Jiras. - RHEL-57466 - autofs crashes on startup after IDM client configuration We have had several different reports caused by this bug which leads to a SEGV with very little information about the cuase. - Resolves: RHEL-57466 - RHEL-69485 - Sporadic mount failures with amd program maps on RHEL8. This bug causes AMD-style program map mounts to sporadically not work. - Resolves: RHEL-69485 - RHEL-71359 - RFE: autofs: add handling for AMD 'nounmount' option This Jira adds support for a map option that was deferred in the original implementtion. One of our customers needs this so it has been implemented. - Resolves: RHEL-71359 Signed-off-by: Ian Kent <ikent@redhat.com>

autofs-5.1.9 - don't free ext mount if mounted
|
|
|
|
From: Ian Kent <raven@themaw.net>
|
|
|
|
If an external mount is in use when a umount is attempted don't free
|
|
it just let the reference count go to zero.
|
|
|
|
This will leave the mount in place and it won't get umounted. But if
|
|
another automount uses it it's reference count will become no zero
|
|
allowing for it to be umounted as normal if it isn't in use during
|
|
automount expire.
