Subject: Loopback, unable to release
Date: Wed, 23 May 2001 11:29:20 -0400 [thread overview]
Message-ID: <3B0BD750.4010306@lycosmail.com> (raw)
Using 2.4.4-ac3 (as well as in 2.4.3*) I have found it impossible to
unmap a loopback
strace losetup -d /dev/loop0 (relevant portion)
open("/dev/loop0", O_RDONLY) = 3
ioctl(3, LOOP_CLR_FD, 0) = -1 EBUSY (Device or resource busy)
open("/usr/share/locale/en_US/LC_MESSAGES/libc.mo", O_RDONLY) = -1
ENOENT (No such file or directory)
open("/usr/share/locale/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT
(No such file or directory)
write(2, "ioctl: LOOP_CLR_FD: Device or re"..., 44ioctl: LOOP_CLR_FD:
Device or resource busy) = 44
_exit(1) = ?
also I have loop.o as module, and use count never decreases, in fact
right now it is at 294.
