f2fs: consider fallocated space for SEEK_DATA
If an amount of data are allocated though fallocate and user writes a couple of data among the space, f2fs should return the data offset made by user when SEEK_DATA is requested. For example, (N: NEW_ADDR by fallocate, X: NEW_ADDR by user) 1) fallocate 0 ~ 10MB f -> N N N N N N N N N N N N ... N 2) write 4KB at 5MB offset f -> N N N N N X N N N N N N ... N 3) SEEK_DATA from 0 should return 5MB offset So, this patch adds a routine to search the first dirty page to handle that. Then, the SEEK_DATA flow skips NEW_ADDR offsets until any dirty page is found. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
