By the way, chunk-based files are all uncompressed for now. +Long extended attribute name prefixes +------------------------------------- +There are use cases where extended attributes with different values can have +only a few common prefixes (such as overlayfs xattrs). The predefined prefixes +work inefficiently in both image size and runtime performance in such cases. + +The long xattr name prefixes feature is introduced to address this issue. The +overall idea is that, apart from the existing predefined prefixes, the xattr +entry could also refer to user-specified long xattr name prefixes, e.g. +"trusted.overlay.". + +When referring to a long xattr name prefix, the highest bit (bit 7) of +erofs_xattr_entry.e_name_index is set, while the lower bits (bit 0-6) as a whole +represent the index of the referred long name prefix among all long name +prefixes. Therefore, only the trailing part of the name apart from the long +xattr name prefix is stored in erofs_xattr_entry.e_name, which could be empty if +the full xattr name matches exactly as its long xattr name prefix. + +All long xattr prefixes are stored one by one in the packed inode as long as +the packed inode is valid, or in the meta inode otherwise. The +xattr_prefix_count (of the on-disk superblock) indicates the total number of +long xattr name prefixes, while (xattr_prefix_start * 4) indicates the start +offset of long name prefixes in the packed/meta inode. Note that, long extended +attribute name prefixes are disabled if xattr_prefix_count is 0. + +Each long name prefix is stored in the format: ALIGN({__le16 len, data}, 4), +where len represents the total size of the data part.

We cannot issue + * discards on extents that might be in use, or are so recently in use they are + * still marked as busy. To serialise against extent state changes whilst we are + * gathering extents to trim, we must hold the AGF lock to lock out other + * allocations and extent free operations that might change extent state. + * + * However, we cannot just hold the AGF for the entire AG free space walk whilst + * we issue discards on each free space that is found. Storage devices can have + * extremely slow discard implementations (e.g. ceph RBD) and so walking a + * couple of million free extents and issuing synchronous discards on each + * extent can take a *long* time. Whilst we are doing this walk, nothing else + * can access the AGF, and we can stall transactions and hence the log whilst + * modifications wait for the AGF lock to be released. This can lead hung tasks + * kicking the hung task timer and rebooting the system. This is bad. + * + * Hence we need to take a leaf from the bulkstat playbook. It takes the AGI + * lock, gathers a range of inode cluster buffers that are allocated, drops the + * AGI lock and then reads all the inode cluster buffers and processes them. It + * loops doing this, using a cursor to keep track of where it is up to in the AG + * for each iteration to restart the INOBT lookup from. + * + * We can't do this exactly with free space - once we drop the AGF lock, the + * state of the free extent is out of our control and we cannot run a discard + * safely on it in this situation.

Hence if we mark the extent as busy under + * the AGF lock, we can safely discard it without holding the AGF lock because + * nothing will attempt to allocate that free space until the discard completes. + * + * This also allows us to issue discards asynchronously like we do with online + * discard, and so for fast devices fstrim will run much faster as we can have + * multiple discard operations in flight at once, as well as pipeline the free + * extent search so that it overlaps in flight discard IO. + */ + +struct workqueue_struct *xfs_discard_wq; + +static void +xfs_discard_endio_work( + struct work_struct *work) +{ + struct xfs_busy_extents *extents = + container_of(work, struct xfs_busy_extents, endio_work); + + xfs_extent_busy_clear(extents->mount, &extents->extent_list, false); + kmem_free(extents->owner); +} + +/* + * Queue up the actual completion to a thread to avoid IRQ-safe locking for + * pagb_lock. + */ +static void +xfs_discard_endio( + struct bio *bio) +{ + struct xfs_busy_extents *extents = bio->bi_private; + + INIT_WORK(&extents->endio_work, xfs_discard_endio_work); + queue_work(xfs_discard_wq, &extents->endio_work); + bio_put(bio); +} + +/* + * Walk the discard list and issue discards on all the busy extents in the + * list.
