All pages that scrub uses in the scrub_block::pagev array are allocated with GFP_KERNEL and never part of any mapping, so kmap is not necessary, we only need to know the page address. In scrub_write_page_to_dev_replace we don't even need to call flush_dcache_page because of the same reason as above. Signed-off-by: NDavid Sterba <dsterba@suse.com>

This patch introduces a new "rescue=" mount option group for all mount options for data recovery. Different rescue sub options are seperated by ':'. E.g "ro,rescue=nologreplay:usebackuproot". The original plan was to use ';', but ';' needs to be escaped/quoted, or it will be interpreted by bash, similar to '|'. And obviously, user can specify rescue options one by one like: "ro,rescue=nologreplay,rescue=usebackuproot". The following mount options are converted to "rescue=", old mount options are deprecated but still available for compatibility purpose: - usebackuproot Now it's "rescue=usebackuproot" - nologreplay Now it's "rescue=nologreplay" Signed-off-by: NQu Wenruo <wqu@suse.com> Reviewed-by: NDavid Sterba <dsterba@suse.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>

We currently use btrfs_check_data_free_space() when allocating space for relocating data extents, but that is not necessary because that function combines btrfs_alloc_data_chunk_ondemand(), which does the actual space reservation, and btrfs_qgroup_reserve_data(). We can use btrfs_alloc_data_chunk_ondemand() directly because we know we do not need to reserve qgroup space since we are dealing with a relocation tree, which can never have qgroups (btrfs_qgroup_reserve_data() does nothing as is_fstree() returns false for a relocation tree). Conversely we can use btrfs_free_reserved_data_space_noquota() directly instead of btrfs_free_reserved_data_space(), since we had no qgroup reservation when allocating space. This change is preparatory work for another patch in this series that makes relocation reserve the exact amount of space it needs to relocate a data block group. The function btrfs_check_data_free_space() has the incovenient of requiring a start offset argument and we will want to be able to allocate space for multiple ranges, which are not consecutive, at once.

The start argument for btrfs_free_reserved_data_space_noquota() is only used to make sure the amount of bytes we decrement from the bytes_may_use counter of the data space_info object is aligned to the filesystem's sector size. It serves no other purpose. All its current callers always pass a length argument that is already aligned to the sector size, so we can make the start argument go away. In fact its presence makes it impossible to use it in a context where we just want to free a number of bytes for a range for which either we do not know its start offset or for freeing multiple ranges at once (which are not contiguous). This change is preparatory work for a patch (third patch in this series) that makes relocation of data block groups that are not full reserve less data space.

Use the helper function where it is open coded to increment the block_group reference count As btrfs_get_block_group() is a one-liner we could have open-coded it, but its partner function btrfs_put_block_group() isn't one-liner which does the free part in it.

__btrfs_return_cluster_to_free_space() returns only 0. And all its parent functions don't need the return value either so make this a void function. Further, as none of the callers of btrfs_return_cluster_to_free_space() is actually using the return from this function, make this function also return void.

Initially when the 'removed' flag was added to a block group to avoid races between block group removal and fitrim, by commit 04216820 ("Btrfs: fix race between fs trimming and block group remove/allocation"), we had to lock the chunks mutex because we could be moving the block group from its current list, the pending chunks list, into the pinned chunks list, or we could just be adding it to the pinned chunks if it was not in the pending chunks list. Both lists were protected by the chunk mutex. However we no longer have those lists since commit 1c11b63e ("btrfs: replace pending/pinned chunks lists with io tree"), and locking the chunk mutex is no longer necessary because of that. The same happens at btrfs_unfreeze_block_group(), we lock the chunk mutex because the block group's extent map could be part of the pinned chunks list and the call to remove_extent_mapping() could be deleting it from that list, which used to be protected by that mutex. So just remove those lock and unlock calls as they are not needed anymore.

When find_first_block_group() finds a block group item in the extent-tree, it does a lookup of the object in the extent mapping tree and does further checks on the item. Factor out this step from find_first_block_group() so we can further simplify the code. While we're at it, we can also just return early in find_first_block_group(), if the tree slot isn't found.

Adresses held in 'logical' array are always guaranteed to fall within the boundaries of the block group. That is, 'start' can never be smaller than cache->start. This invariant follows from the way the address are calculated in btrfs_rmap_block: stripe_nr = physical - map->stripes[i].physical; stripe_nr = div64_u64(stripe_nr, map->stripe_len); bytenr = chunk_start + stripe_nr * io_stripe_size; I.e it's always some IO stripe within the given chunk. Exploit this invariant to simplify the body of the loop by removing the unnecessary 'if' since its 'else' part is the one always executed.

extent_map::orig_block_len contains the size of a physical stripe when it's used to describe block groups (calculated in read_one_chunk via calc_stripe_length or calculated in decide_stripe_size and then assigned to extent_map::orig_block_len in create_chunk). Exploit this fact to get the size directly rather than opencoding the calculations. No functional changes.

The call to btrfs_btree_balance_dirty has been there since the early days of BTRFS, when the btree was directly modified from the write path, hence dirtied btree inode pages. With the implementation of b888db2b ("Btrfs: Add delayed allocation to the extent based page tree code") 13 years ago the btree is no longer modified from the write path, hence there is no point in calling this function.

Currently, maximum physical memory allowed is equal to -PAGE_OFFSET. That's why we remove any memory blocks spanning beyond that size. However, it is done only for memblock containing linux kernel which will not work if there are multiple memblocks. Process all memory blocks to figure out how much memory needs to be removed and remove at the end instead of updating the memblock list in place.

It also improves the initrd placement by aligning the start and size with the page size.
