Rick Macklem cf766161ff For software builds, the NFS client does many small ... synchronous (with FILE_SYNC) writes because non-contiguous byte ranges in the same buffer cache block are being written. This patch adds a new mount option "noncontigwr" which allows the non-contiguous byte ranges to be combined, with the dirty byte range becoming the superset of the bytes that are dirty, if the file has not been file locked. This reduces the number of writes significantly for software builds. The only case where this change might break existing applications is where an application is writing non-overlapping byte ranges within the same buffer cache block of a file from multiple clients concurrently. Since such an application would normally do file locking on the file, avoiding the byte range merge for files that have been file locked should be sufficient for most (maybe all?) cases.
