The expression 'indata[3] > ULONG_MAX' always evaluates to false since
indata[] is declared as an array of *unsigned long* elements and #define
ULONG_MAX represents the max value of that exact type...
Note that gcc seems to be able to detect the dead code here and eliminate
this check anyway...

Hi,
I am going to add +Jahdiel Alvarez who is also looking into a similar
issue, and also I would like to hear thoughts of people who may have
worked with (embedded or otherwise) storage more recently than I have
One thought that Jahdiel and myself were pondering is whether we need
"type_a" and "t

Until now, the allocation of the in-core bitmaps was done in pre-resume
by metadata_resize().
In preparation for the next commit, which makes it possible for a
metadata operation, e.g. an era rollover, to run before pre-resume runs,
allocate the in-core bitmaps as part of opening the metadata.

Under certain conditions, swapping a table, that includes a dm-era
target, with a new table, causes a deadlock.
This happens when a status (STATUSTYPE_INFO) or message IOCTL is blocked
in the suspended dm-era target.
dm-era executes all metadata operations in a worker thread, which stops

Hi Chaitanya, thanks for bringing this up! I definitely want to join and learn
from the discussions. Here I note my comments about them.
