2024-12-27xfs: create a new helper to return a file's allocation unitDarrick J. Wong
commit ee20808d848c87a51e176706d81b95a21747d6cf upstream. [backport: dependency of d3b689d and f23660f] Create a new helper function to calculate the fundamental allocation unit (i.e. the smallest unit of space we can allocate) of a file. Things are going to get hairy with range-exchange on the realtime device, so prepare for this now. Remove the static attribute from xfs_is_falloc_aligned since the next patch will need it.

2024-12-27xfs: declare xfs_file.c symbols in xfs_file.hDarrick J. Wong
commit 00acb28d96746f78389f23a7b5309a917b45c12f upstream. [backport: dependency of d3b689d and f23660f] Move the two public symbols in xfs_file.c to xfs_file.h. We're about to add more public symbols in that source file, so let's finally create the header file. Signed-off-by: Darrick J.
