Hello,
At file.c:306
inline_size = end_pos;
if (isize >= BTRFS_MAX_INLINE_DATA_SIZE(root) ||
inline_size > 32768 ||
inline_size >= BTRFS_MAX_INLINE_DATA_SIZE(root))
When 'end_pos' is larger than 2^32, 'inline_size' may become a small
value. In this case, 'dirty_and_release_pages' may try to insert a
very large inline extent.
Regards
YZ
