| 228 | generic_file_write() is only appropriate for filesystems that are not seeking to optimize performance and want |
| 229 | something simple that works. It is not for serious use by general purpose filesystems, excepting the one that it was |
| 230 | written for (ext2/3). This is for several reasons: |
| 231 | |
| 232 | * It has no understanding of any filesystem specific optimizations. |
| 233 | |
| 234 | * It enters the filesystem repeatedly for each page that is written. |
| 235 | |
| 236 | * It depends on reiserfs_get_block() function which if implemented by reiserfs performs costly search_by_key |
| 237 | * operation for each page it is supplied with. By contrast reiserfs_file_write() feeds as much as possible at a time |
| 238 | * to reiserfs which allows for fewer tree traversals. |
| 239 | |
| 240 | * Each indirect pointer insertion takes a lot of cpu, because it involves memory moves inside of blocks. |
| 241 | |
| 242 | * Asking the block allocation code for blocks one at a time is slightly less efficient. |
| 243 | |
| 244 | All of these reasons for not using only generic file write were understood back when reiserfs was first miscoded to |
| 245 | use it, but we were in a hurry to make code freeze, and so it couldn't be revised then. This new code should make |
| 246 | things right finally. |
| 247 | |
| 248 | Future Features: providing search_by_key with hints. |
