syslog: I think this might speed upt the CR-LF scan in syslog_dev_write().

syslog: There is yet another place where the output can get split. That is in syslog_dev_write(): It will break up the stream to insert a CR before the LF. This can that can be avoid be generating the CR-LF sequence in the buffer and then detecting and ignoring valid CR-LF sequences, rather than expecting syslog_dev_write() to insert the CR in this case.
...
I don't like the idea that syslog_dev_write() still scans the entire output buffer to expand CR-LF sequence. This seems really wasteful, especially in this case where we can be sure that the is no CR or LF without a matching LF or CR. Bu, I think, the existing behavior in syslog_dev_write() must be retained because it is needed in other contexts.

SYSLOG logic should use existing file interfaces, not re-invent them.

syslog_dev_flush() needs to check if the inode is a mountpoint before calling the flush() method. Noted by David Sidrane.

There is now one-and-only-one copy of syslog_putc. It is in the SYSLOG channel logic and can redirect syslog output as needed. All former syslog_putc versions were renamed and the corresponding SYSLOG device initializaiton now calls syslog_channel()

Some renaming so that future features will fit in better; If the architecture provides its only system logging (via CONFIG_ARCH_SYSLOG), then syslog_initialize() is stubbed out

Add a hook before the existing syslog_initialize() call; rename the old syslog_initialize() to syslog_dev_initialize().
