[PATCH v2 0/4] libcamera: Address soft ISP file seal TODO item

[Laurent Pinchart]

Hello,

This small series addresses one TODO item of the soft ISP, namely shrink
and grow sealing of the memfd underlying SharedMem objects.

Patch 1/4 starts by sharing the memfd handling code between the
DmaBufAllocator and SharedMem classes by moving it to a new MemFd helper
class. Patch 2/4 then applies a suggestion from Nicolas to improve code
readability. Patch 3/4 addresses the TODO item, and patch 4/4 finally
drops it from the TODO file.

Could someone test this with the soft ISP to make sure I haven't broken
anything ?

  libcamera: base: memfd: Handle uClibc compatibility with function
    wrapper
