f2fs: don't worry about inode leak in evict_inode

2016-05-07T17:32:30+00:00

Even if an inode failed to release its blocks, it should be kept in an orphan inode list, so it will be released later. Signed-off-by: Jaegeuk Kim

f2fs: revisit error handling flows

2016-05-07T17:32:25+00:00

This patch fixes a couple of bugs regarding to orphan inodes when handling errors. This tries to - call alloc_nid_done with add_orphan_inode in handle_failed_inode - let truncate blocks in f2fs_evict_inode - not make a bad inode due to i_mode change Signed-off-by: Jaegeuk Kim

fs crypto: move per-file encryption from f2fs tree to fs/crypto

2016-03-18T04:19:33+00:00

This patch adds the renamed functions moved from the f2fs crypto files. 1. definitions for per-file encryption used by ext4 and f2fs. 2. crypto.c for encrypt/decrypt functions a. IO preparation: - fscrypt_get_ctx / fscrypt_release_ctx b. before IOs: - fscrypt_encrypt_page - fscrypt_decrypt_page - fscrypt_zeroout_range c. after IOs: - fscrypt_decrypt_bio_pages - fscrypt_pullback_bio_page - fscrypt_restore_control_page 3. policy.c supporting context management. a. For ioctls: - fscrypt_process_policy - fscrypt_get_policy b. For context permission - fscrypt_has_permitted_context - fscrypt_inherit_context 4. keyinfo.c to handle permissions - fscrypt_get_encryption_info - fscrypt_free_encryption_info 5. fname.c to support filename encryption a. general wrapper functions - fscrypt_fname_disk_to_usr - fscrypt_fname_usr_to_disk - fscrypt_setup_filename - fscrypt_free_filename b. specific filename handling functions - fscrypt_fname_alloc_buffer - fscrypt_fname_free_buffer 6.

f2fs: split drop_inmem_pages from commit_inmem_pages

2016-02-23T00:07:23+00:00

Split drop_inmem_pages from commit_inmem_pages for code readability, and prepare for the following modification. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: use wait_for_stable_page to avoid contention

2016-02-23T00:07:23+00:00

In write_begin, if storage supports stable_page, we don't need to wait for writeback to update its contents. This patch introduces to use wait_for_stable_page instead of wait_on_page_writeback. Signed-off-by: Jaegeuk Kim

f2fs: avoid multiple node page writes due to inline_data

2016-02-23T00:07:23+00:00

The sceanrio is: 1. create fully node blocks 2. flush node blocks 3. write inline_data for all the node blocks again 4. flush node blocks redundantly So, this patch tries to flush inline_data when flushing node blocks. Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim
