Hi - We are writing a file system in which we need to read/write blocks of size greater than or equal to 4K in one go. As far as my understanding is we can read 4K in one go throug buffer cache. Can any one suggest a way ( alternate or throug buffer cache) to do it. Thanks in advance -- ----------- S K T ----------- -- Kernelnewbies: Help each other learn about the Linux kernel.
