The ramoops driver prepends a "====timestamp.timestamp-C|D\n"
|
||||
header to the compressed record before handing it over to pstore
|
||||
driver which doesn't know about the header. In pstore_decompress(),
|
||||
the pstore driver reads the first "==" as a zlib header, so the
|
||||
decompression always fails. For example, this causes the driver
|
||||
to write /dev/pstore/dmesg-ramoops-0.enc.z instead of
|
||||
/dev/pstore/dmesg-ramoops-0.
|
||||
|
||||
This patch makes the ramoops driver remove the header before
|
||||
pstore decompression.
