Subject: [PATCH v2 0/2] powerpc/fadump: remove deprecated sysfs compatibility links
Date: Mon, 13 Jul 2026 09:56:33 +0530 [thread overview]
Message-ID: <20260713042636.1599868-1-sourabhjain@linux.ibm.com> (raw)
The FADump sysfs interface was reorganized in 2019 by moving the
/sys/kernel/fadump_* files under /sys/kernel/fadump/ and marking the
old paths as deprecated. Compatibility symlinks were retained to avoid
breaking existing userspace.
The following deprecated compatibility symlinks are removed by this
series:
/sys/kernel/fadump_enabled
/sys/kernel/fadump_registered
/sys/kernel/fadump_release_mem
The corresponding supported interfaces remain:
/sys/kernel/fadump/enabled
/sys/kernel/fadump/registered
/sys/kernel/fadump/release_mem
The major userspace consumers have since been updated to use the new
interface, and the deprecated paths have remained supported for several
years. This series completes the transition by removing the compatibility
symlinks and updating the documentation to reference only the current
sysfs interface.
