Patch 2/4 then applies a suggestion from Nicolas to improve code\nreadability. Patch 3/4 addresses the TODO item, and patch 4/4 finally\ndrops it from the TODO file.\n\nCould someone test this with the soft ISP to make sure I haven't broken\nanything ?\n\nLaurent Pinchart (4):\n libcamera: base: Add MemFd helper class\n libcamera: base: memfd: Handle uClibc compatibility with function\n wrapper\n libcamera: shared_mem_object: Prevent memfd from shrinking or growing\n libcamera: software_isp: Remove file seal TODO item\n\n include/libcamera/base/memfd.h | 34 ++++++++\n include/libcamera/base/meson.build | 1 +\n src/libcamera/base/memfd.cpp | 123 ++++++++++++++++++++++++++++\n src/libcamera/base/meson.build | 1 +\n src/libcamera/dma_buf_allocator.cpp | 46 +----------\n src/libcamera/shared_mem_object.cpp | 22 ++---\n src/libcamera/software_isp/TODO | 19 -----\n 7 files changed, 169 insertions(+), 77 deletions(-)\n create mode 100644 include/libcamera/base/memfd.h\n create mode 100644 src/libcamera/base/memfd.cpp\n\n\nbase-commit: 98b01768397f982bd177b55e9bc67002b645b4d0"}
