The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the node release code to a separate function broke death notifications in some cases. When it encountered a reference without a death notification request, it would skip looking at the remaining references, and therefore fail to send death notifications for them.

commit e194fd8a5d8e0a7eeed239a8534460724b62fe2d upstream.

The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.

staging: android: logger: Correct write offset reset on error 2013-08-04T08:50:51+00:00 Karlis Ogsts karlis.ogsts@sonymobile.com 2013-07-22T20:51:42+00:00 dbc31d4e7958e7539180b9f2d7c8446e4a0429d4 commit 72bb99cfe9c57d2044445fb34bbc95b4c0bae6f2 upstream. In the situation that a writer fails to copy data from userspace it will reset the write offset to the value it had before it went to sleep. This discarding any messages written while aquiring the mutex. Therefore the reset offset needs to be retrieved after acquiring the mutex.

In the situation that a writer fails to copy data from userspace it will reset
the write offset to the value it had before it went to sleep. This discarding
any messages written while aquiring the mutex.
