Aruna Balakrishnaiah b0aad7a99c pstore: Add compression support to pstore ... Add compression support to pstore which will help in capturing more data. Initially, pstore will make a call to kmsg_dump with a bigger buffer and will pass the size of bigger buffer to kmsg_dump and then compress the data to registered buffer of registered size. In case compression fails, pstore will capture the uncompressed data by making a call again to kmsg_dump with registered_buffer of registered size. Pstore will indicate the data is compressed or not with a flag in the write callback.
