Currently, we will check if inode layout is compression or inline if the inode is special in fill_inode(). Also set ->i_mapping->a_ops for it. That is pointless since the both modes won't be set for special inode when creating EROFS filesystem image. So, let's avoid it. Signed-off-by:

We should consider the error returned by fill_inline_data() when filling last page in fill_inode(). If not getting inode will be successful even though last page is bad. That is illogical. Also change -EAGAIN to 0 in fill_inline_data() to stand for successful filling. Signed-off-by:

An earlier patch I sent reduced the stack usage enough to get below the warning limit, and I could show this was safe, but with GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, it gets worse again because large stack variables in the same function no longer overlap: drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'translate_scan.isra.2': drivers/staging/rtl8712/rtl871x_ioctl_linux.c:322:1: error: the frame size of 1200 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Split out the largest two blocks in the affected function into two separate functions and mark those noinline_for_stack. Fixes: 8c5af16f ("staging: rtl8712: reduce stack usage") Fixes: 81a56f6d ("gcc-plugins: structleak: Generalize to all variable types") Signed-off-by:

Decompressor needs to know whether it's a partial or full decompression since only full decompression can be decompressed in-place. On kirin980 platform, sequential read is finally increased to 812MiB/s after decompression inplace is enabled. Reviewed-by:

This patch integrates new decompression framework to erofs decompression path, and remove the old decompression implementation as well. On kirin980 platform, sequential read is slightly improved to 778MiB/s after the new decompression backend is used. Reviewed-by:

compressed data will be usually loaded into last pages of the extent (the last page for 4k) for in-place decompression (more specifically, in-place IO), as ilustration below, start of compressed logical extent | end of this logical extent | | ______v___________________________v________ ... | page 6 | page 7 | page 8 | page 9 | ... |__________|__________|__________|__________| . ^ . ^ . |compressed| . | data | . . . |< dstsize >|<margin>| oend iend op ip Therefore, it's possible to do decompression inplace (thus no memcpy at all) if the margin is sufficient and safe enough [1], and it can be implemented only for fixed-size output compression compared with fixed-size input compression. No memcpy for most of in-place IO (about 99% of enwik9) after decompression inplace is implemented and sequential read will be improved of course (see the following patches for test results).

This patch adds a new generic decompression framework in order to replace the old LZ4-specific decompression code. Even though LZ4 is still the only supported algorithm, yet it is more cleaner and easy to integrate new algorithm than the old almost hard-coded decompression backend. Reviewed-by:

stagingpages are behaved as bounce pages for temporary use. Move to compress.h since the upcoming decompressor will allocate stagingpages as well. Reviewed-by:

This patch moves per-CPU buffers to utils.c in order for the upcoming generic decompression framework to use it. Note that I tried to use generic per-CPU buffer or per-CPU page approaches to clean up further, but obvious performanace regression (about 2% for sequential read) was observed. Therefore let's leave it as it is instead, just move to utils.c and I'll try to dig into the root cause later. Signed-off-by:
