Andrea Righi f20c4b0c01 module/decompress: use vmalloc() for gzip decompression workspace ... [ Upstream commit 3737df782c ] Use a similar approach as commit a419beac4a ("module/decompress: use vmalloc() for zstd decompression workspace") and replace kmalloc() with vmalloc() also for the gzip module decompression workspace. In this case the workspace is represented by struct inflate_workspace that can be fairly large for kmalloc() and it can potentially lead to allocation errors on certain systems: $ pahole inflate_workspace struct inflate_workspace { struct inflate_state inflate_state; /* 0 9544 */ /* --- cacheline 149 boundary (9536 bytes) was 8 bytes ago --- */ unsigned char working_window[32768]; /* 9544 32768 */ /* size: 42312, cachelines: 662, members: 2 */ /* last cacheline: 8 bytes */ }; Considering that there is no need to use continuous physical memory, simply switch to vmalloc() to provide a more reliable in-kernel module decompression.
