2024-01-28modpost: Add '.ltext' and '.ltext.*' to TEXT_SECTIONSNathan Chancellor1-1/+2
After the linked LLVM change, building ARCH=um defconfig results in a segmentation fault in modpost. Prior to commit a23e7584ecf3 ("modpost: unify 'sym' and 'to' in default_mismatch_handler()"), there was a warning: WARNING: modpost: vmlinux.o(__ex_table+0x88): Section mismatch in reference to the .ltext:(unknown) WARNING: modpost: The relocation at __ex_table+0x88 references section ".ltext" which is not in the list of authorized sections. If you're adding a new section and/or if this reference is valid, add ".ltext" to the list of authorized sections to jump to on fault. This can be achieved by adding ".ltext" to OTHER_TEXT_SECTIONS in scripts/mod/modpost.c. The linked LLVM change moves global objects to the '.ltext' (and '.ltext.*' with '-ffunction-sections') sections with '-mcmodel=large', which ARCH=um uses. These sections should be handled just as '.text' and '.text.*' are, so add them to TEXT_SECTIONS.

2024-01-28um: Fix adding '-no-pie' for clangNathan Chancellor1-1/+3
The kernel builds with -fno-PIE, so commit 883354afbc10 ("um: link vmlinux with -no-pie") added the compiler linker flag '-no-pie' via cc-option because '-no-pie' was only supported in GCC 6.1.0 and newer. While this works for GCC, this does not work for clang because cc-option uses '-c', which stops the pipeline right before linking, so '-no-pie' is unconsumed and clang warns, causing cc-option to fail just as it would if the option was entirely unsupported: $ clang -Werror -no-pie -c -o /dev/null -x c /dev/null clang-16: error: argument unused during compilation: '-no-pie' [-Werror,-Wunused-command-line-argument] A recent version of clang exposes this because it generates a relocation under '-mcmodel=large' that is not supported in PIE mode: /usr/sbin/ld: init/main.o: relocation R_X86_64_32 against symbol `saved_command_line' can not be used when making a PIE object; recompile with -fPIE /usr/sbin/ld: failed to set dynamic section sizes: bad value clang: error: linker command failed with exit code 1 (use -v to see invocation) Remove the cc-option check altogether. It is wasteful to invoke the compiler to check for '-no-pie' because only one supported compiler version does not support it, GCC 5.x (as it is supported with the minimum version of clang and GCC 6.1.0+). Use a combination of the gcc-min-version macro and CONFIG_CC_IS_CLANG to unconditionally add '-no-pie' with CONFIG_LD_SCRIPT_DYN=y, so that it is enabled with all compilers that support this. Furthermore, using gcc-min-version can help turn this back into LINK-$(CONFIG_LD_SCRIPT_DYN) += -no-pie when the minimum version of GCC is bumped past 6.1.0.

2024-01-21bcachefs: Prep work for variable size btree node buffersKent Overstreet18-97/+87
bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate.

2024-01-21bcachefs: Avoid flushing the journal in the discard pathKent Overstreet1-19/+41
When issuing discards, we may need to flush the journal if there's too many buckets that can't be discarded until a journal flush. But the heuristic was bad; we should be comparing the number of buckets that need to flushes against the number of free buckets, not the number of buckets we saw.

2024-01-21bcachefs: Improve move_extent tracepointKent Overstreet5-7/+48
Also print out the data_opts, so that we can see what specifically is being done to an extent. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: Add missing bch2_moving_ctxt_flush_all()Kent Overstreet1-0/+1
This fixes a bug with rebalance IOs getting stuck with reads completed, but writes never being issued. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: Re-add move_extent_write tracepointKent Overstreet2-23/+20
It appears this was accidentally deleted at some point - also, do a bit of cleanup. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amountKent Overstreet1-2/+2
Drop t he loop in bch2_kthread_io_clock_wait(): this allows the code that uses it to be woken up for other reasons, and fixes a bug where rebalance wouldn't wake up when a scan was requested. This raises the possibility of spurious wakeups, but callers should always be able to handle that reasonably well. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-01-21bcachefs: Don't pass memcmp() as a pointerKent Overstreet1-2/+8
Some (buggy!) compilers have issues with this. Fixes: https://github.com/koverstreet/bcachefs/issues/625 Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: Reduce would_deadlock restartsKent Overstreet1-0/+7
We don't have to take locks in any particular ordering - we'll make forward progress just fine - but if we try to stick to an ordering, it can help to avoid excessive would_deadlock transaction restarts. This tweaks the reflink path to take extents btree locks in the right order. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: bch2_trans_account_disk_usage_change()Kent Overstreet3-29/+48
The disk space accounting rewrite is splitting out accounting for each replicas set - those are moving to btree keys, instead of percpu counters. This breaks bch2_trans_fs_usage_apply() up, splitting out the part we will still need. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: bch_fs_usage_baseKent Overstreet7-47/+45
Split out base filesystem usage into its own type; prep work for breaking up bch2_trans_fs_usage_apply(). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-21bcachefs: bch2_prt_compression_type()Kent Overstreet5-6/+15

2024-01-21bcachefs: helpers for printing data typesKent Overstreet14-64/+64
We need bounds checking since new versions may introduce new data types. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-01-21bcachefs: Don't log errors if BCH_WRITE_ALLOC_NOWAITKent Overstreet1-4/+5
Previously, we added logging in the write path to ensure that any unexpected errors getting reported to userspace have a log message; but BCH_WRITE_ALLOC_NOWAIT is a special case, it's used for promotes where errors are expected and not reported out to userspace - so we need to silence those.
