Subject: [PATCH 12/46] debugfs: fix parse_uint for 64-bit fields
|
|
|
f239de |
Content-Type: text/plain

The logic for handling 64-bit structure elements was reversed, which
|
|
|
f239de |
caused attempts to set fields like kbytes_written to fail:
|
|
|
f239de |
|
|
|
f239de |
% debugfs -w /tmp/foo.img
|
|
|
f239de |
debugfs 1.45.6 (20-Mar-2020)
|
|
|
f239de |
debugfs: set_super_value kbytes_written 1024
|
|
|
f239de |
64-bit field kbytes_written has a second 64-bit field
|
|
|
f239de |
defined; BUG?!?
