Subject: [PATCH 0/6] hfsplus: convert regular file I/O to iomap-based operations
Date: Wed, 22 Jul 2026 14:37:52 -0700 [thread overview]
Message-ID: <20260722213759.1360225-1-slava@dubeyko.com> (raw)
This series moves HFS+ regular file data I/O off the legacy
buffer_head/blockdev_direct_IO() path onto iomap-based operations with
the goal to retire the older buffer_head-based direct I/O infrastructure.
Patchset is based on for-next branch of HFS/HFS+ git tree [1].
[1] https://git.kernel.org/pub/scm/linux/kernel/git/vdubeyko/hfs.git/
Viacheslav Dubeyko (6):
hfs/hfsplus: exchange hardcoded number of extents on named constants
hfsplus: rework hfsplus_get_block() logic
hfsplus: take the bitmap page lock for allocate/free
hfsplus: add iomap operations for regular file data
hfsplus: add iomap-based file_operations
hfsplus: switch address_space_operations on iomap-based support
