If an application - wants to read a small file, it can finish its job with just a lookup - call instead of a lookup followed by read. - -- getdents/setdents - - These are used by unify to set and get directory entries. - -- ALIGN_BUF - - Macro to align an address to a page boundary (4K). - -- priv->export_statfs - - In some cases, two exported volumes may reside on the same - partition on the server. Sending statvfs info for both - the volumes will lead to erroneous df output at the client, - since free space on the partition will be counted twice. - - In such cases, user can disable exporting statvfs info - on one of the volumes by setting this option. - -- xattrop - - This fop is used by replicate to set version numbers on files. - -- getxattr/setxattr hack to read/write files - - A key, GLUSTERFS_FILE_CONTENT_STRING, is handled in a special way by - getxattr/setxattr. A getxattr with the key will return the entire - content of the file as the value. A setxattr with the key will write - the value as the entire content of the file. - -- posix_checksum - - This calculates a simple XOR checksum on all entry names in a - directory that is used by unify to compare directory contents. - - |
