Bug Description

[In:5.5:Dump/Restore of the Buffer Pool]

The definition at the bottom is wrong, it is a copy of the one for innodb_auto_lru_dump. It should be something like:

"We this variable is set, Percona Server will reload at startup the pages from the last lru dump."

The documentation is correct, innodb_buffer_pool_restore_at_startup is the 5.5 name for innodb_auto_lru_dump, and the renaming happened in 5.5.10-20.1.

The variable (innodb_buffer_pool_restore_at_startup in 5.5 or innodb_auto_lru_dump in 5.1) controls both automatic buffer pool dumps and automatic restore on startup. This behavior was a deliberate decision and is described in the manual as well.

Though I agree the new name is not quite consistent with its help and functionality.

  --innodb-buffer-pool-restore-at-startup=#
                      Time in seconds between automatic buffer pool dumps. 0
                      (the default) disables automatic dumps.

We can keep this bug report as a request to improve that.
