2012-12-10ext4: let ext4_readdir handle inline dataTao Ma1-0/+136
For "." and "..", we just call filldir by ourselves instead of iterating the real dir entry. Signed-off-by: Tao Ma <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
2012-12-10ext4: let add_dir_entry handle inline data properlyTao Ma1-0/+377
This patch let add_dir_entry handle the inline data case. So the dir is initialized as inline dir first and then we can try to add some files to it, when the inline space can't hold all the entries, a dir block will be created and the dir entry will be moved to it. Also for an inlined dir, "." and ".." are removed and we only use 4 bytes to store the parent inode number. These 2 entries will be added when we convert an inline dir to a block-based one. [ Folded in patch from Dan Carpenter to remove an unused variable. ] Signed-off-by: Tao Ma <[email protected]> Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
2012-12-10ext4: add delalloc support for inline dataTao Ma1-0/+177
For delayed allocation mode, we write to inline data if the file is small enough. And in case of we write to some offset larger than the inline size, the 1st page is dirtied, so that ext4_da_writepages can handle the conversion. When the 1st page is initialized with blocks, the inline part is removed. Signed-off-by: Tao Ma <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
2012-12-10ext4: add journalled write support for inline dataTao Ma1-0/+24

2012-12-10ext4: add normal write support for inline dataTao Ma1-0/+233
For a normal write case (not journalled write, not delayed allocation), we write to the inline if the file is small and convert it to an extent based file when the write is larger than the max inline size. Signed-off-by: Tao Ma <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
2012-12-10ext4: add read support for inline dataTao Ma1-0/+61
Let readpage and readpages handle the case when we want to read an inlined file. Signed-off-by: Tao Ma <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
2012-12-10ext4: add the basic function for inline data supportTao Ma1-0/+466
Implement inline data with xattr. Now we use "system.data" to store xattr, and the xattr will be extended if the i_size is increased while we don't release the space during truncate. Signed-off-by: Tao Ma <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
