[ Upstream commit4b9fc71462] Before the commit490ea5967b("RDS: IB: move FMR code to its own file"), when the dirty_count is greater than 9/10 of max_items of 8K pool, 1M pool is used, Vice versa. After the commit490ea5967b("RDS: IB: move FMR code to its own file"), the above is removed. When we make the following tests. Server: rds-stress -r 1.1.1.16 -D 1M Client: rds-stress -r 1.1.1.14 -s 1.1.1.16 -D 1M The following will appear. " connecting to 1.1.1.16:4000 negotiated options, tasks will start in 2 seconds Starting up..header from 1.1.1.166:4001 to id 4001 bogus .. tsks tx/s rx/s tx+rx K/s mbi K/s mbo K/s tx us/c rtt us cpu % 1 0 0 0.00 0.00 0.00 0.00 0.00 -1.00 1 0 0 0.00 0.00 0.00 0.00 0.00 -1.00 1 0 0 0.00 0.00 0.00 0.00 0.00 -1.00 1 0 0 0.00 0.00 0.00 0.00 0.00 -1.00 1 0 0 0.00 0.00 0.00 0.00 0.00 -1.00 ... " So this exchange between 8K and 1M pool is added back.

These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
