Subject: [PATCH 0/3] better error messages for ioctls
Date: Fri, 29 Aug 2025 02:54:04 -0400 [thread overview]
Message-ID: <20250829065409.3248746-1-kent.overstreet@linux.dev> (raw)
This fixes a common user complaint - uninformative error messages from
various bcachefs-tools commands.
Add v2 versions of various ioctls that include a 'struct
bch_ioctl_err_mesg', a pointer to a userspace buffer for an error
message - and plumb a printbuf through various code for returning
errors.
Kent Overstreet (3):
bcachefs: Add v2 ioctls that return error strings
bcachefs: v2 versions of subvolume ioctls
bcachefs: Plumb error messages through data drop paths
