VFS will take inode_lock for readdir, therefore no need to take page lock in readdir at all just as the majority of other generic filesystems. This patch improves concurrency since .iterate_shared was introduced to VFS years ago.

We use below condition to check inline_xattr_size boundary: if (!F2FS_OPTION(sbi).inline_xattr_size || F2FS_OPTION(sbi).inline_xattr_size >= DEF_ADDRS_PER_INODE - F2FS_TOTAL_EXTRA_ATTR_SIZE - DEF_INLINE_RESERVED_SIZE - DEF_MIN_INLINE_SIZE) There is there problems in that check: - we should allow inline_xattr_size equaling to min size of inline {data,dentry} area. - F2FS_TOTAL_EXTRA_ATTR_SIZE and inline_xattr_size are based on different size unit, previous one is 4 bytes, latter one is 1 bytes. - DEF_MIN_INLINE_SIZE only indicate min size of inline data area, however, we need to consider min size of inline dentry area as well, minimal inline dentry should at least contain two entries: '.' and '..', so that min inline_dentry size is 40 bytes. .bitmap 1 * 1 = 1 .reserved 1 * 1 = 1 .dentry 11 * 2 = 22 .filename 8 * 2 = 16 total 40 Signed-off-by: NChao Yu <yuchao0@huawei.com> Signed-off-by: NJaegeuk Kim <jaegeuk@kernel.org>

Previously, we changed lock from cp_rwsem to node_change, it solved the deadlock issue which was caused by below race condition: Thread A Thread B - f2fs_setattr - f2fs_lock_op -- read_lock - dquot_transfer - __dquot_transfer - dquot_acquire - commit_dqblk - f2fs_quota_write - f2fs_write_begin - f2fs_write_failed - write_checkpoint - block_operations - f2fs_lock_all -- write_lock - f2fs_truncate_blocks - f2fs_lock_op -- read_lock But it breaks the sematics of cp_rwsem, in other callers like: - f2fs_file_write_iter -> f2fs_write_begin -> f2fs_write_failed - f2fs_direct_IO -> f2fs_write_failed We allow to truncate dnode w/o cp_rwsem held, result in incorrect sit bitmap update, which can cause further data corruption. So this patch reverts previous fix implementation, and try to fix deadlock by skipping calling f2fs_truncate_blocks() in f2fs_write_failed() only for quota file, and keep the preallocated data/node in the tail of quota file, we can expecte that the preallocated space can be used to store quota info latter soon.
