init, Documentation: Remove ramdisk_blocksize mentions
The brd driver has never supported the ramdisk_blocksize kernel parameter that was in the rd driver it replaced, so remove mention of this parameter from comments and Documentation. Commit 9db5579be4bb ("rewrite rd") replaced rd with brd, keeping a brd_blocksize variable in struct brd_device but never using it. Commit a2cba2913c76 ("brd: get rid of unused members from struct brd_device") removed the unused variable. Commit f5abc8e75815 ("Documentation/blockdev/ramdisk.txt: updates") removed mentions of ramdisk_blocksize from that file. Signed-off-by: Robert Elliott <> Signed-off-by: Jonathan Corbet <>
