Subject: erofs-utils: lib: shorten EROFS_FRAGMENT_INMEM_SZ_MAX
X-Git-Tag: accepted/tizen/unified/20250610.081809~36
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3051162fefef9af9f274266a2ad9d5d612d50ccc;p=platform%2Fupstream%2Ferofs-utils.git

erofs-utils: lib: shorten EROFS_FRAGMENT_INMEM_SZ_MAX

EROFS_CONFIG_COMPR_MAX_SZ (currently 4MiB) is too large and could
cause OOM kills on small setups.
