| 279 | block truncatation on error exit from ->write_begin, and ->direct_IO | ||
| 280 | moved from generic methods (block_write_begin, cont_write_begin, | ||
| 281 | nobh_write_begin, blockdev_direct_IO*) to callers. Take a look at | ||
| 282 | ext2_write_failed and callers for an example. | ||
| 283 | |||
| 284 | [mandatory] | ||
| 285 | |||
| 286 | ->truncate is going away. The whole truncate sequence needs to be | ||
| 287 | implemented in ->setattr, which is now mandatory for filesystems | ||
| 288 | implementing on-disk size changes. Start with a copy of the old inode_setattr | ||
| 289 | and vmtruncate, and the reorder the vmtruncate + foofs_vmtruncate sequence to | ||
| 290 | be in order of zeroing blocks using block_truncate_page or similar helpers, | ||
| 291 | size update and on finally on-disk truncation which should not fail. | ||
| 292 | inode_change_ok now includes the size checks for ATTR_SIZE and must be called | ||
| 293 | in the beginning of ->setattr unconditionally. | ||
| 294 | |||
| 295 | [mandatory] | ||
| 296 | |||
| 297 | ->clear_inode() and ->delete_inode() are gone; ->evict_inode() should | ||
| 298 | be used instead. It gets called whenever the inode is evicted, whether it has | ||
| 299 | remaining links or not. Caller does *not* evict the pagecache or inode-associated | ||
| 300 | metadata buffers; getting rid of those is responsibility of method, as it had | ||
| 301 | been for ->delete_inode(). | ||
| 302 | ->drop_inode() returns int now; it's called on final iput() with inode_lock | ||
| 303 | held and it returns true if filesystems wants the inode to be dropped. As before, | ||
| 304 | generic_drop_inode() is still the default and it's been updated appropriately. | ||
| 305 | generic_delete_inode() is also alive and it consists simply of return 1. Note that | ||
| 306 | all actual eviction work is done by caller after ->drop_inode() returns. | ||
| 307 | clear_inode() is gone; use end_writeback() instead. As before, it must | ||
| 308 | be called exactly once on each call of ->evict_inode() (as it used to be for | ||
| 309 | each call of ->delete_inode()). Unlike before, if you are using inode-associated | ||
| 310 | metadata buffers (i.e. mark_buffer_dirty_inode()), it's your responsibility to | ||
| 311 | call invalidate_inode_buffers() before end_writeback(). | ||
| 312 | No async writeback (and thus no calls of ->write_inode()) will happen | ||
| 313 | after end_writeback() returns, so actions that should not overlap with ->write_inode() | ||
| 314 | (e.g. freeing on-disk inode if i_nlink is 0) ought to be done after that call. | ||
| 315 | |||
| 316 | NOTE: checking i_nlink in the beginning of ->write_inode() and bailing out | ||
| 317 | if it's zero is not *and* *never* *had* *been* enough. Final unlink() and iput() | ||
| 318 | may happen while the inode is in the middle of ->write_inode(); e.g. if you blindly | ||
| 319 | free the on-disk inode, you may end up doing that while ->write_inode() is writing | ||
| 320 | to it. | ||
